• DIY Electronic Vehicle Rust Prevention

    From Computer Nerd Kev@3:633/280.2 to All on Sun Feb 25 14:34:47 2024
    While looking into rust-proof paints, I stumbled upon the world of
    electronic rust prevention gadgets: https://www.erps.com.au/how-electronic-rust-protection-works/ https://endrust.com.au/products-services/Electronic-Rust-Protection/ https://nilrust.com.au/product-details/electronic-rustproofing/
    etc.

    Much like with the paints, the question is whether it works, or
    whether it's just snake oil. It's supposed to use conductive pads
    to create a static charge on the steel vehicle body by using the
    paint as a dilectric layer forming a capacitor. The charge prevents
    oxidation of the metal.

    In this discussion it's mentioned that by relying on the paint to
    form the dilectric, it won't work in areas where the paint is weak,
    which is where rust would start anyway: https://www.electro-tech-online.com/threads/electronic-rust-protection-for-cars.13859/

    Then again much of my trouble is from cavities in old vehicle
    bodies rusting out from inside*. The paint on the outside is OK
    until the rust eats right through, so would the electric charge
    prevent that rust starting on the inner side?

    This also says "There are to date no official reports which show
    that cars with electronic rust proofing have less corrosion than
    they would without the device": https://www.autotrainingcentre.com/blog/truth-electronic-rust-protection/

    On that basis I certainly wouldn't buy one at the prices these
    systems are advertised at, but it seems they should be temptingly
    easy to make, and maybe try out in some experiments.

    I can't find any DIY designs online, but the specifications on this
    page suggests that the electronics just make a 50V peak-to-peak AC
    voltage at 12.5KHz which is applied to the adheasive contact pads
    (copper tape?): https://endrust.com.au/product/2-pad-cat-electronic-rust-protection-system/
    Input Voltage > 12V/24VDC
    Operating Voltage > 9V-32VDC
    Output Transformers > Two (2)
    Output Power (to each Pad) > 50Vpk-pk @ 12.5kHz
    Ground > Negative
    Current Draw > 25ma +/-

    If that's all there is to it, then it shouldn't be hard to build my
    own equivalent.

    Anyone know of existing DIY projects or authoritative proof that it
    doesn't (or does!) work?

    * Waxy cavity coatings like this were actually what I was
    investigating when I stumbled onto these gizmos:

    I am pretty sure it was denounced as a scam years ago. When I last
    searched for it, up came an Isuzu dealer in NSW who was still selling it
    as an add-on.

    I've found where Wikipedia has this technology filed: https://en.wikipedia.org/wiki/Cathodic_protection#Automobiles

    The PDFs in the references are very interesting. This summarises
    one of the scientific tests and also reveals the waveform of
    another system. 10V 3us pulses at 10KHz, which is rather
    different to the other specs. That signal would be even easier
    to generate.

    Don't waste your time. It's already been done. They don't work.

    The best prevention against rust is to ensure that the metal is
    adequately coated with something that forms a durable and effective
    moisture barrier, and while electric processes exist to remove rust,
    there are none that prevent rust from occurring.

    Reading the Wikipedia article and looking through the references has
    encouraged me. At least the two Canadian devices that had lab tests
    done seemed to make a difference, in an area where the paint was
    scratched through. They tested with salt spray though, whereas I
    just want to protect against normal dampness and trapped moisture.

    I'd like to try the same test leaving some scratched steel panels
    outside for a month or two connected to different
    signals/voltages/electrodes. I'm not sure where to find scrap sheet
    metal with good paint though. Perhaps if I can get a broken fridge
    off someone?

    When I last searched for it, up came an Isuzu dealer in NSW who
    was still selling it as an add-on.

    There seem to be plenty of rust-preventative businesses selling
    them all over Aus. But I guess we don't have the same laws as
    Canada requiring public proof of their effectiveness, and I haven't
    seen one that actually guarantees your car won't rust, just that
    the device itself won't stop (not?) working.

    The only experiments I have found online, via the Wikipedia article
    I found later, say the (Canadian) devices do work! So which ones
    say they don't?

    adequately coated with something that forms a durable and effective
    moisture barrier,

    Well I'm better with a soldering iron than a spray can, and there
    are some places that a spray can won't reach anyway (which is what
    I was looking into those wax spray substances for).

    and while electric processes exist to remove rust,
    there are none that prevent rust from occurring.

    I hadn't looked into removing rust electrically either actually,
    but it looks like that'd require dunking your car in a tank of
    water. I'll stick to rust converter goos and a Dremmel.

    Noting that the King of snake oil bullshit boasting is none other than yourself! You, a parasite on the arse of the motor trade, with no trade qualifications to speak of, trying to pretend you are an *authority* on
    rust prevention processes! FFS, you only ever attended a hobby course at Richmond TAFE in vehicle body repair and spray painting and now you're
    trying to make yourself out as a *experience professional*? Don't make

    If they did work they would be very popular in places like the UK or Nth America where they get snow and ice on the roads treated with salt and
    they don't seem to be popular in those places.

    That's exactly the sort of non-evidence that makes me want to test
    it out myself. On the one hand there are tests accepted by the
    Canadian regulators as proof of effectiveness, and on the other
    hand "they don't seem to be popular". I sure wouldn't pay hundreds
    for one, but if the root of the thing is just applying simple
    electrical signals to the paint surface, it's an easy thing to test
    a DIY equivalent on some bits of scrap. Some of the patents contain
    useful details.

    But if there are actual records of people doing such tests and
    showing that it's all lies, which I can see myself (not just hear
    rumor of), then I wouldn't.

    That may just be because the car manufacturers currently

    I have added alt.home.repair which has lots of north americans

    only work in practice if the car it was attached to was submerged in water.

    Thanks, however that's the same thing the Canadian regulator
    claimed, as reported on the Wikipedia page. Then the Canadians
    backed down when two of the manufacturers there had tests done
    by recognised labs showing that their particular devices did
    reduce rust.

    It could be that the Aussie devices are/were doing it wrong, or
    those tests didn't represent read-world conditions, but I'd like
    to see actual tests disproving the Canadian claims seeing
    as their authorities had to back down on the "broken theory"
    argument. For now I'm focusing on those as the devices
    to try and replicate based on patents and the test reports.

    The thing that makes me most suspicious is that they're charging
    $300-$1000+ for these systems which so far as I can see would cost
    a tenth of that or less to make. That sort of profiteering suggests
    some dodgyness. But then again the same's probably true of many
    paints and anti-rust "treatments".

    Government consumer protection agencies would *not* be ordering these products off the market and people to be refunded if they worked.

    It's that simple....

    Ah yeah, but the Canadians are *not* doing that anymore,
    therefore...

    Note: WA comsumer protection laws habe also prevent unqualified

    Different story in backward Victoria where unqualified and incompetent

    Stick to whatever you like, but there are no electronic rust

    Canada proves that that is a lie.

    All Canada has ever proved is that people can survive in minus 40 degree temperatures, and all you ever continue to prove is that you're a

    While looking into rust-proof paints, I stumbled uponthe world of
    electronic rust prevention gadgets:
    https://www.erps.com.au/how-electronic-rust-protection-works/
    https://endrust.com.au/products-services/Electronic-Rust-Protection/
    https://nilrust.com.au/product-details/electronic-rustproofing/
    etc.

    Much like with the paints, the question is whether it works, or
    whether it's just snake oil.

    Rust preventing paint certainly does work.

    I built my house in the very early 70s and the entire
    structure is RHS, and did the two big gates out of
    RHS too. Used killrust paint and nothing has rusted
    in what is now more than 50 years.

    And my 2006 Hyundai Getz has not rust at all, not
    even the decent gouge that some arsehole managed
    to do in the woolys car park right in the middle of the
    driver's door, with what appears to have been the
    corner of a ute flat tray. And I have done nothing to
    protect the gouge at all.

    Yes I don't disagree at all that a good paint job works wonders,
    but once it starts to wear down the ideal solution is to pull the
    thing completely to pieces, sand blast it, and paint again. I'm
    interested in whether these devices can help put that stage off
    a bit longer, because it isn't going to happen.

    I'd still keep grinding out and painting over rust spots where
    they're found. In places I can't get to I've been spraying fish
    oil, though I'm thinking about using these wax sprays for a more
    permanent fix. Painting over fish oil has also lasted on the cab
    of an 80s truck I tried that on a few years ago. New rust in
    different spots has started to appear though, as it does.

    It's supposed to use conductive pads
    to create a static charge on the steel vehicle body by using the
    paint as a dilectric layer forming a capacitor. The charge prevents
    oxidation of the metal.

    Can't see that and my formal qualifications are in chemistry.

    OK. Some documents suggest it helps the zinc in paint or galvalised
    steel to protect the steel more effectively, but there doesn't seem
    to be a concrete theory.

    In this discussion it's mentioned that by relying on the paint to
    form the dilectric, it won't work in areas where the paint is weak,
    which is where rust would start anyway:
    https://www.electro-tech-online.com/threads/electronic-rust-protection-for-cars.13859/

    What is the detail of the car ? Modern
    cars are much better than the old ones.

    These are 80s and 90s vehicles. All kept under roofs but open to
    the elements.

    Then again much of my trouble is from cavities in old vehicle
    bodies rusting out from inside*. The paint on the outside is OK
    until the rust eats right through, so would the electric charge
    prevent that rust starting on the inner side?

    This also says "There are to date no official reports which show
    that cars with electronic rust proofing have less corrosion than
    they would without the device": https://www.autotrainingcentre.com/blog/truth-electronic-rust-protection/

    On that basis I certainly wouldn't buy one at the prices these
    systems are advertised at, but it seems they should be temptingly
    easy to make, and maybe try out in some experiments.

    I can't find any DIY designs online, but the specifications on this
    page suggests that the electronics just make a 50V peak-to-peak AC
    voltage at 12.5KHz which is applied to the adheasive contact pads
    (copper tape?): https://endrust.com.au/product/2-pad-cat-electronic-rust-protection-system/
    Input Voltage > 12V/24VDC
    Operating Voltage > 9V-32VDC
    Output Transformers > Two (2)
    Output Power (to each Pad) > 50Vpk-pk @ 12.5kHz
    Ground > Negative
    Current Draw > 25ma +/-

    If that's all there is to it, then it shouldn't be hard to build my
    own equivalent.

    Anyone know of existing DIY projects or authoritative proof that it
    doesn't (or does!) work?

    * Waxy cavity coatings like this were actually what I was
    investigating when I stumbled onto these gizmos:

    If it worked, every ship owner in the world would be using it.
    Sacrificial anodes work under water, but ship's topsides still rust, and require constant re-painting.

    only work in practice if the car it was attached to was submerged in water.

    Thanks, however that's the same thing the Canadian regulator
    claimed, as reported on the Wikipedia page. Then the Canadians
    backed down when two of the manufacturers there had tests done
    by recognised labs showing that their particular devices did
    reduce rust.

    It could be that the Aussie devices are/were doing it wrong, or
    those tests didn't represent read-world conditions, but I'd like
    to see actual tests disproving the Canadian claims seeing
    as their authorities had to back down on the "broken theory"
    argument. For now I'm focusing on those as the devices
    to try and replicate based on patents and the test reports.

    The thing that makes me most suspicious is that they're charging
    $300-$1000+ for these systems which so far as I can see would cost
    a tenth of that or less to make. That sort of profiteering suggests
    some dodgyness. But then again the same's probably true of many
    paints and anti-rust "treatments".

    Government consumer protection agencies would *not* be ordering these
    products off the market and people to be refunded if they worked.

    It's that simple....

    ever seen in newsgroups (proven), means that anything he utters on
    pretty much any topic has to be taken with a truckload of salt.

    ps. Easy to get rid of him, just ask him to stump up proof of his past

    make the bastard killfile you and run away as fast as his little legs

    Do you live near the coast where rust might be a problem?
    Rust on cars hasn't been a significant issue in Australia for many many
    years, in general our climate isn't damp enough for it to be an issue
    and car rust proofing from the factory is much improved.
    I own 2 cars that are more than 20yrs old and no rust on either of them
    so whether or not those electronic rust devices work is pretty much
    irrelevant to most car owners.
    Popularity or not is an indication of their effectiveness, whilst it
    certainly isn't a scientific test its a good indication of whether or
    not they work, if they did work and there was lots of anecdotal evidence
    then they would sell a lot more, the fact that they aren't almost
    standard in places that have lots of car rust is a pretty good
    indication that they simply don't work as advertised.

    Sounds like he's trying to treat some older trucks that already have
    rust issues and I don't think that those devices are going to be much
    help on a vehicle that already has significant rust.
    The XD panelvan that I owned many years ago had quite a bit of rust in
    the bottom of the doors when I bought it, I cleared the blocked drain
    holes, got rid of as much of the surface rust as possible then treated
    the area with fish oil which stopped the rust from getting any worse.

    I didn't want opinions, I wanted authoritative proof. I did find
    some of that in the Canadian tests, saying that the devices do
    work, though I _am_ still skeptical. You told me experiments had
    been tried and failed, but no references to who/what/when/where.

    I also thought there might have been DIY projects online or in

    I've always got rust repairs to amuse myself with.

    Maybe. Frankly I'm fed up with rust, so with the information
    suggesting they might work, it looks worth a try to me. I could be
    convinced otherwise, but not just by apparant popularity.

    It was common on older vehicles and 80's is old for vehicles.
    Last vehicle that I owned that had significant rust problems was a 1979 Landcruiser, nothing structural, mostly below the tail lamps and the
    bonnet, had the rust fixed properly by a good panel beater and resprayed
    and there was no sign of the rust returning when I sold it many years later.

    Doubt that its much dryer approx 55km west of Melb CBD.
    Do you drive a lot on dirt roads?
    If so its possible that the dirt/mud gets stuck under the vehicle and
    stays damp which causes rust, periodically cleaning underneath may be a
    way of reducing rust problems.

    A neighbour has
    similar rust problems developing on a late 80s truck, which spent

    Yes the vehicles I have the rust problems with are from the 80s and

    I can see how it might not be useful.

    OK, maybe the climate is more dry where you live.

    Doubt that its much dryer approx 55km west of Melb CBD.
    Do you drive a lot on dirt roads?
    If so its possible that the dirt/mud gets stuck under the vehicle and
    stays damp which causes rust, periodically cleaning underneath may be a
    way of reducing rust problems.

    Yes, I live on a gravel road and am aware of that, but the rust
    issues are usually with the upper body, not so bad underneath or
    in wheel arches. Only the outer layer of dust/clay stays damp where
    it builds up underneath, the clay in the soil resists the moisture
    penetrating back.

    I'm pretty sure that at least one vehicle where I've had rust
    _is_ made of galvanised steel.

    What make and model?

    OK well I'm asking for trouble with that one really because it's a
    1989 Jaguar XJ40. Then there's a 1996 Nissan Navara ute where the once-galvanised tray is most of the trouble, but the cab's started
    showing surface rust lately too. The truck is a 1980 International
    ACCO 610A, where the cab is possibly better than most others still
    out there, but that still makes it pretty rusty.

    Shed floor concrete or dirt/gravel?

    Gravel.

    Also I check out the Manheim car auctions and they get a regular
    stream of rust buckets.

    Yep. Except for a 2010s Land Cruiser I saw on their website,

    The XD panelvan that I owned many years ago had quite a bit of rust in

    the area with fish oil which stopped the rust from getting any worse.

    Google should have told you all you needed to know. As others have said,

    I did find some of that in the Canadian tests, saying that the

    If this is the kind of Canadian testing you're talking about, then the

    You told me experiments had been tried and failed, but no references

    and

    NSW Fair Trading Commissioner Rod Stowe has warned NSW consumers not

    I also thought there might have been DIY projects online or in

    And why do you think that is?

    Just go ahead and do your testing Kev. Sounds like you have little

    An "80's Land Cruiser" is a 40 year old vehicle :)

    Rust on cars hasn't been a significant issue in Australia for many many
    years, in general our climate isn't damp enough for it to be an issue
    and car rust proofing from the factory is much improved.
    I own 2 cars that are more than 20yrs old and no rust on either of them
    so whether or not those electronic rust devices work is pretty much
    irrelevant to most car owners.

    OK, maybe the climate is more dry where you live. A neighbour has
    similar rust problems developing on a late 80s truck, which spent
    almost all its life in a shed (though not fully enclosed). I'm
    pretty sure that at least one vehicle where I've had rust _is_
    made of galvanised steel.

    Again, anything made in the 1980's is 40 years old, and rust in vehicles
    of that age is not uncommon. Some vehicles are quite famous for it.

    Secondly, galvanised steel is not a common car body material. At least
    not where high levels of zinc are concerned. The main reason for that is
    that Zinc and paint don't happily co-exist. Automotive body
    manufacturers for the last 50 years at least have been using cold rolled
    steel for most of their body pressings, which is subject to an "e-coat" process that uses small quantities of zinc and other materials to
    provide a corrosion protection layer.

    It's a form of "galvanising" per se', but it's nothing like the kind of
    Zinc based glavanising you commonly see on things like trailers, tools
    and bolts.

    Also I check out the Manheim car auctions and they get a regular
    stream of rust buckets.

    Do they?

    Popularity or not is an indication of their effectiveness, whilst it
    certainly isn't a scientific test its a good indication of whether or

    suggesting they might work, it looks worth a try to me. I could be
    convinced otherwise, but not just by apparant popularity.

    Interesting. You have virtually *nothing* to convince you that the
    process is either successful *or* popular but because you found a link
    to some sketchy testing that suggests that it *might* work you're
    willing to forgo tried and tested methods and pursue an "easy" option.

    Good luck with your projects :)

    Two of those three vehicles are world famous for rust issues. Your

    own which were poorly built heaps of crap that are so notorious for rust issues that they would corrode in a hermetically sealed vacuum.

    No, of course I'm not willing to forgo tried and tested methods. I'm
    willing to do a test on scrap metal because it seems nobody has
    published such tests except those ones you call sketchy which say
    it works. Either way I'll still keep treating any rust I encounter conventionally.

    Good luck with your projects :)

    It'll be a fun electronics experiment. One of my more practical
    ones overall.

    That's exactly the sort of non-evidence that makes me want to test
    it out myself. On the one hand there are tests accepted by the
    Canadian regulators as proof of effectiveness, and on the other
    hand "they don't seem to be popular".

    That may just be because the car manufacturers currently
    do a good enough job with the paint so they aren't necessary

    I have added alt.home.repair which has lots of north americans
    and likely Clare Snyder who is actually a male, whose first name
    is Clarence who is a very experience mechanic may comment.

    I sure wouldn't pay hundreds
    for one, but if the root of the thing is just applying simple
    electrical signals to the paint surface, it's an easy thing to test
    a DIY equivalent on some bits of scrap. Some of the patents contain
    useful details.

    But if there are actual records of people doing such tests and
    showing that it's all lies, which I can see myself (not just hear
    rumor of), then I wouldn't.

    A friend of mine tested this in the lab when I was in college. The
    devices don't work. They've been around for decades and they've never
    worked.

    He wrote a paper on it for the class he was in, but I don't think it was
    ever published since it just debunked some junk science and didn't
    actually represent any new and valuable research in terms of chemistry.

    Seems to be some debate on whether or not Jags were actually galvanized. https://www.jaguarforum.com/threads/galvanised-body-fact-or-myth.44736/

    Then there's a 1996 Nissan Navara ute where the
    once-galvanised tray is most of the trouble,

    Once galvanized indicates that much of the gal has been rubbed off?
    If so bare steel doesn't have much rust resistance.

    but the cab's started
    showing surface rust lately too.

    It is almost 30yrs old so not surprising that there is some rust.

    The truck is a 1980 International
    ACCO 610A, where the cab is possibly better than most others still

    Salt water will destroy even the very best vehicles so that really

    body but not too bad, it was used as a beach tour vehicle and spent
    nearly its entire life on a beach, Ford replaced the chassis under warranty. >>>> Popularity or not is an indication of their effectiveness, whilst it

    That's exactly the sort of non-evidence that makes me want to test
    it out myself. On the one hand there are tests accepted by the
    Canadian regulators as proof of effectiveness, and on the other
    hand "they don't seem to be popular".

    That may just be because the car manufacturers currently
    do a good enough job with the paint so they aren't necessary

    I have added alt.home.repair which has lots of north americans
    and likely Clare Snyder who is actually a male, whose first name
    is Clarence who is a very experience mechanic may comment.

    I sure wouldn't pay hundreds
    for one, but if the root of the thing is just applying simple
    electrical signals to the paint surface, it's an easy thing to test
    a DIY equivalent on some bits of scrap. Some of the patents contain
    useful details.

    But if there are actual records of people doing such tests and
    showing that it's all lies, which I can see myself (not just hear
    rumor of), then I wouldn't.

    A friend of mine tested this in the lab when I was in college. The
    devices don't work. They've been around for decades and they've never
    worked.

    Got technical info on just how they operate - *in detail*?


    He wrote a paper on it for the class he was in, but I don't think it was
    ever published since it just debunked some junk science and didn't
    actually represent any new and valuable research in terms of chemistry.

    Given the *lack of evidence*, I kind of expected your comment to be unbacked/unpublished. No surprise there, eh?

    Interesting. You have virtually *nothing* to convince you that the

    willing to forgo tried and tested methods and pursue an "easy" option.

    No, of course I'm not willing to forgo tried and tested methods. I'm
    willing to do a test on scrap metal because it seems nobody has
    published such tests except those ones you call sketchy which say
    it works. Either way I'll still keep treating any rust I encounter conventionally.

    Good luck with your projects :)

    It'll be a fun electronics experiment. One of my more practical
    ones overall.

    Yeah, I don't think so, but anyway. It would seem that the lack of any
    success stories about this shit tells you nothing.

    That article is slightly misrepresenting the actual notice from the Commissioner for Consumer Protection: https://www.commerce.wa.gov.au/sites/default/files/atoms/files/highperfcorpmotoroneeuoct15.pdf

    That document doesn't say anything about "proof" that the
    devices don't work, just that those companies making them hadn't
    a basis for claiming they did. In other words, presumably, those
    companies hadn't done satisfactory testing themselves. It's the
    same as in Canada where two manufacturers responded to the same
    thing with actual tests proving that their devices did work, and
    their authorities relented.

    That's explained very clearly in this letter sent by the Canadian
    Competition Bureau: https://www.autosaverobd.com/wp-content/uploads/2023/02/Let_Competition-Bureau_17Jul2008.pdf

    So I intend to copy the design of those Canadian devices.

    The "proof" was just disputing the theory. I don't call that a
    "test". I guess you must use the word
    differently.

    Proving something doesn't work is a little more than just disputing the theory.

    EXACTLY, that's why I'm interested in doing my own tests to prove
    it to my own satisfaction. Frankly I'm still skeptical of the
    Canadian tests, but short of finding other real experiments
    documented (and I only found those Canadian ones by clicking through
    two other Wikipedia pages about rust in general), they're the last
    word on the matter. That I can find.

    Actual tests: https://www.autosaverobd.com/wp-content/uploads/2023/02/ITS-REPORT-015-05015-4-_3-15-2007_.pdf

    The problem with doing any sort of testing in an automotive environment
    is that there are a lot of variables, the steel is not all exactly the
    same and the way they its treated also varies, the environment that cars
    live in can also vary considerably.
    You may have success testing a device on one car but a failure on an
    another making it very difficult to be 100% sure whether or not the
    device works.
    Testing will be a bit like testing those kangaroo whistles that we
    fitted to the front of our cars, we didn't hit any kangaroos so did they
    work or did we just get lucky.

    My idea is that I fix any existing rust like I've been doing, then
    the device (if I can make one that seems to work in my tests) helps
    resist new rust spots appearing in completely different areas.
    Hopefully the repaired areas too.

    Indeed that's why I intend to test it first away from a car like I
    said before in my reply to Ozix. Inspired heavily by the tests the
    Canadians did, but without the salt spray. Similar to this, but
    without the humidity-controlled chamber so it might take many
    months just being left outside (avoiding bird poo might be a
    problem):
    https://www.finalcoat.com/assets/lab_tests/Smithers.pdf

    That'll also allow testing different signals and voltages.

    Mind you, I won't be able to use automotive sheet metal and paint
    like in their tests. Testing on individual car body panels like
    undamaged doors removed from the same old car might be better,
    but I don't know where I'd get those cheap locally. The idea is to
    scratch them and then watch for rust developing in the scratch.

    It might be because on ships, unless the superstructure is
    electrically insulated from the hull, any exposed metal (eg. from
    chipped paint) on the hull would conduct through the salt water
    between the paint and the metal, shorting out the capacitive
    charge between them which the device creates.

    But that's guesswork. I'm most interested to see documented studies

    It seems strange that I've owed a car for 17 years and when scrapped
    because of mechanical problems that were uneconomic to fix there wasn't
    a trace of rust on any of the body panels. My car wasn't fitted with one
    of these anti-rust wonder products. Perhaps European car manufactures
    take a lot more care with the paint technology and build quality?

    In general, from what I see on certain Youtube videos cars that spend
    most of their life in somewhere like Florida have little underbody rust whereas the same car model that has spent its life in a state where the
    roads need to be salted for most of the winter have a significant amount
    of rust. Even on fairly young cars the effort required to remove fixings (bolts etc.) to replace components is higher on cars that have spent
    their life further North.

    How representative of rust problems on cars is the test detailed above performed on two body panels? The main problem is not necessarily body
    panels but rust destroying chassis parts etc. beneath the car.

    Perhaps or because cars in Europe are subject to harsh winter conditions
    they take more care with body protection.
    No such problem where I live in Melbourne Australia, our 3 cars are all
    German and not a spec of rust on any of them, 2 of them are 2002 models.
    I've noticed that the paint on all 3 is hard compared to other cars I've
    owned especially Japanese cars, unsure whether that makes any difference.

    Nope, nothing strange about that.

    Clearly not true of Jags and the BMC crap.

    Well BMC hasn't existed for over 50 years, nor has its successor British Leyland which included Jaguar and Landrover.

    Currently these brands are owned by Tata and whist the build quality has improved, security hasn't and Range Rovers are almost uninsurable...

    ... modern Jags seem as rust proof as any other car.

    OK well I'm asking for trouble with that one really because it's a
    1989 Jaguar XJ40.

    Seems to be some debate on whether or not Jags were actually galvanized.
    https://www.jaguarforum.com/threads/galvanised-body-fact-or-myth.44736/

    OK, it looked galvanised in a wheel arch where some of the
    undercoat was chipped off, and there was no rust there even though
    the metal was (or at least looked) exposed. Probably just in
    certain spots like the forum thread says.

    It most likely was galvanised and, I might add, the Jaguar was one of
    the forerunners in a process that became common during the 90s. Pretty
    much every car this century has been hot dipped galvanized and that
    process began in the US and AU around 1995.
    The problem with paint as a protective barrier against corrosion is that
    it needs 100% coverage. A scratch or stone chip is all that is needed to provide a start point for rust to begin attacking the base metal
    underneath - so you once needed to fix up stone chips and scratches immediately.
    Enter the galvanising process. Cars tend to be hot dipped because it is
    the easiest process and the coating is thicker - that's important. The
    layer of zinc functions first as a barrier, just like paint, to those atmospheric components that would like to react with the iron - water
    being the perfect example. Secondly the chemical reaction of the zinc
    with, say, the water, creates a thin layer best known as a patina. In
    this process the water splits into ions and reacts with the zinc thereby creating the "protective" patina layer. This patina forms a second
    barrier to keep the underlying steel free of rust. Thirdly, there is
    cathodic protection. In the electrochemical reaction, the cathode
    (steel) gets protected whilst the anode (zinc) gets sacrificed. Because
    of the hot dipped galvanizing, the paint coat on modern cars is purely decorative.
    That sacrifice is important to note - because it is time constrained.
    Car bodies will be protected for some 30 years and, by then, enough of
    the zinc will have been sacrificed for rust to begin to take over. At 30 years, most cars would be well and truly past their use by date and well
    on their way to being a recycled Chinese car. So, if you have a car
    older than 30 years, it might be time to pay more attention to rust
    prevention and general maintenance.

    This reminds me of a little debacle with a Chinese ute on the Gold Coast recently;

    https://www.queenslandjudgments.com.au/caselaw/qcat/2021/316

    Was the LDV ute hot dipped galvanised? I suspect it wasn't. Or if it
    was, it was a piss poor job.



    Then there's a 1996 Nissan Navara ute where the
    once-galvanised tray is most of the trouble,

    Once galvanized indicates that much of the gal has been rubbed off?
    If so bare steel doesn't have much rust resistance.

    but the cab's started
    showing surface rust lately too.

    It is almost 30yrs old so not surprising that there is some rust.



    I'm not surprised either. Such are valid use cases for a rust
    prevention device _if_ they worked, which was my only point.

    The truck is a 1980 International
    ACCO 610A, where the cab is possibly better than most others still
    out there, but that still makes it pretty rusty.

    Those trucks were notorious for rust, finding one without significant
    rust would be near impossible.

    Yes I more or less said that. At least the steel is farly thick so
    there's some time to catch it before you get a hole.

    Any vehicle from the 70s or 80s was notorious for rust. Note too, most
    of these rusted *from the inside* exacerbated by lack of owner attention
    to cleaning out mud collection points, unblocking drain holes, and the like.

    I won't be that surprised if it doesn't do anything, but since I
    haven't seen any tests showing that they don't work, I'd like to
    find out for sure.


    Worth a try if you have some spare time, just don't hold your breath
    expecting much of a result.

    Sure, I enjoy electronics tinkering anyway. More fun than arguing
    over what consitiutes an experiment/test, but I guess I forgot that
    aus.cars is only a place for arguments.

    Because of environmental laws, there is likely to be less variation
    in paint types used.

    https://en.wikipedia.org/wiki/Automotive_paint

    Cars are designed for global markets. If you are Tata, you don't
    design a car and only test it in Mumbai. Say the boss says "let's sell
    this car in Canada". If you are the responsible engineer, you can't
    say to the boss "but, but, it will need to be tested in Finland
    for cold start, and that will mean a one year wait for test completion".

    Instead, you have to do your best, to design cars that work anywhere,
    by testing them in extreme conditions. As a Mumbai car driver, you can
    take comfort that your car starts in Finland.

    The body work on cars, doesn't rust like it once did.

    The frame and underneath of a car, that's another matter entirely.

    You can replace all the suspension components on a car, during it life.
    The coil springs can crack and need replacement (I had a cracked one). McPherson struts used to pop through, during a car life, but today,
    as you're taking the car to the junk yard, the cap on the strut is
    just starting to rust.

    The bottom of a car, can be treated with undercoat. But, the treatment
    types should be consistent. If you use a wax treatment, if the company
    goes out of business, you need to find another company that uses wax
    coats during touchups. This is why in some cases, you're just as well
    off with oil spray treatments once or twice a year. There are more places
    that will do oil.

    An oil spray starts with a cleaning, followed by the oil. And it's a selective treatment, as you can't spray it on some things without damaging them.

    And that should be enough. No need for gizmos or snake oil.

    If only that were true. It was once, but not these days :)

    Like any other consumer product today, cars are designed to a price
    point and most of today's testing is simulated. The problem with that is
    that simulations will only ever pick up faults that the creators of the testing program have anticipated as being possible, which explains why
    we see cars today fail within a short time with ridiculous issues that
    would have been picked up in any kind of real world testing like that
    which was carried out years ago.

    In today's world it's all about money. Manufacturers want the fastest
    return they can get on their R&D dollar, so they simulate the bulk of
    their testing and get the car onto the market as quickly as possible so
    they can start earning sales revenue. In doing so they use the initial
    buyers as beta testers, and as faults present themselves they
    incorporate the fixes into the subsequent updated models.

    The body work on cars, doesn't rust like it once did.

    I assure you that steel bodywork used on cars today will rust just as
    quickly as it did in years gone by *if* it's exposed to the same levels
    of moisture that older cars were.

    Apart from using thinner materials, there has been no major change in
    sheet metal processes in the last 50 years as far as car bodies are
    concerned. Where change *has* occurred is in the area of weather
    protection. Cars today are very well sealed against road grime and
    moisture compared to years ago with all kinds of inner splash shields,
    seals, deflectors, under body trays, you name it. All of it designed to
    keep mud, water, grime or what have you from finding it's way into nooks
    and crannies where it can sit and eat away at the metal and create a
    hole where one isn't supposed to be.

    The frame and underneath of a car, that's another matter entirely.

    The overwhelming majority of cars built in the last 5 decades don't have
    a "frame". They are Unibody construction, with the entire body made of
    sheet metal.

    You can replace all the suspension components on a car, during it life.
    The coil springs can crack and need replacement (I had a cracked one). McPherson struts used to pop through, during a car life, but today,
    as you're taking the car to the junk yard, the cap on the strut is
    just starting to rust.

    Not sure what you're on about here....

    The bottom of a car, can be treated with undercoat. But, the treatment
    types should be consistent. If you use a wax treatment, if the company
    goes out of business, you need to find another company that uses wax
    coats during touchups. This is why in some cases, you're just as well
    off with oil spray treatments once or twice a year. There are more places that will do oil.

    Car bodies are corrosion dipped at the factory during their manufacture.

    An oil spray starts with a cleaning, followed by the oil. And it's a selective
    treatment, as you can't spray it on some things without damaging them.

    And that should be enough. No need for gizmos or snake oil.

    Sounds like you're talking about after market processes here, and if you
    are then don't waste your money on oils or waxes as they're not very effective. If you're in an environment where you need to use a third
    party under body coating, then the very best product you can ever use is
    body deadener, which in parts of the world is known as "body shultz".

    It's a bitumen based rubberised coating that is *extremely* durable. It
    only ever needs to be applied once, it is ridiculously effective and if
    done correctly it will outlive the car.

    I certainly wouldn't want my body parts treated in that manner.

    Car bodies in white are washed before rust proofing to remove any oil contamination.

    It seems strange that I've owed a car for 17 years and when scrapped

    a trace of rust on any of the body panels. My car wasn't fitted with one
    of these anti-rust wonder products. Perhaps European car manufactures
    take a lot more care with the paint technology and build quality?

    In general, from what I see on certain Youtube videos cars that spend
    most of their life in somewhere like Florida have little underbody rust
    whereas the same car model that has spent its life in a state where the
    roads need to be salted for most of the winter have a significant amount
    of rust. Even on fairly young cars the effort required to remove fixings
    (bolts etc.) to replace components is higher on cars that have spent
    their life further North.

    How representative of rust problems on cars is the test detailed above
    performed on two body panels? The main problem is not necessarily body
    panels but rust destroying chassis parts etc. beneath the car.

    My Citroen XM had a zinc plated body and doors.

    Renault was also doing this galvanizing the whole welded body. Some are
    on sided galvanized before welding.

    When the body in white is dipped in the phosphatizing treatment then
    ELPO bubbles trapped may prevent treatment. I recall cars in the rust
    belt rusting on top of the fenders. They eventually remedied this.

    Your rust problems are caused by poor designed and built. You will not
    solve your problems with electronic snake oil. You will *only* solve
    your problems by dismantling the vehicle to the point where the known problem areas can be dressed and coated with an effective durable
    moisture barrier, and then sealing the area to prevent ingress.

    The hope is to reduce things like the little bubble of rust I
    recently noticed on top of the 1996 Nissan Navara's roof which mean
    it's time to add that cab to my patient's list for such rust
    repairs. I doubt that's one of the "poor designed and built"
    vehicles you mean either.

    OK your opinion is that it's not worth testing, got it. I didn't
    ask for that opinion anyway, I was only interested in published
    tests and DIY projects. So forget about it.

    Those tests with salt spray are therefore actually less

    They're not popular because they _don't_ _work_.

    This is really basic. There is no magical process that prevents metal corrosion in free air, and if all it took was a 10 buck rectifier to
    prevent vehicles from rusting manufacturers would have given up on the expensive process of multiple anti corrosion body dips on the assembly
    line and just used one of these magical devices instead :)

    The devices were tested on metals that have had the anti-corrosion
    treatment and it's suggested in the scientific papers that they
    require it.

    Still true Darren. Before it is launched a new vehicle is tested
    virtually (simulation) and then finally on the road with development
    mules. That still happens today. 40 years ago I was at the Holden
    Development Labs watching vehicles being tested with CAE (Computer Aided Engineering). Today that is more sophisticated but vehicles are still
    tested on the road.

    Like any other consumer product today, cars are designed to a price
    point and most of today's testing is simulated. The problem with that is that simulations will only ever pick up faults that the creators of the testing program have anticipated as being possible, which explains why
    we see cars today fail within a short time with ridiculous issues that
    would have been picked up in any kind of real world testing like that
    which was carried out years ago.

    The cars of yore were often stymied by problems that *should have* been
    picked up in testing - but weren't. I was working in dealerships in the
    late 60s and 70s seeing these failures first hand. The problems we have
    in new cars nowadays are nothing like the cockups that occurred in the
    70s. A good example was the twisting chassis caused by steering box
    applied forces on HJ Holdens. Didn't have that issue on the earlier
    models. You never worked *as a mechanic* in a dealership so how do you
    know what was going on in the car industry back in the day?

    In today's world it's all about money. Manufacturers want the fastest
    return they can get on their R&D dollar, so they simulate the bulk of
    their testing and get the car onto the market as quickly as possible so
    they can start earning sales revenue. In doing so they use the initial buyers as beta testers, and as faults present themselves they

    Sorry but I have to disabuse you of that idea. The development mules are
    used for that purpose - and test areas like Lang Lang. Even the motoring writers can be seen as beta testers

    The body work on cars, doesn't rust like it once did.

    I assure you that steel bodywork used on cars today will rust just as quickly as it did in years gone by *if* it's exposed to the same levels
    of moisture that older cars were.

    Nope. Quality of steel is the first point. The second are the coatings applied. Cars do not rust at anywhere near the rust rates of *last century*.

    Apart from using thinner materials, there has been no major change in
    sheet metal processes in the last 50 years as far as car bodies are concerned. Where change *has* occurred is in the area of weather

    Bullshit. Are you claiming to be an *expert* in sheet metal processes
    now? A mate here has been in the panel beating game for over 50 years
    and he told me there have been heaps of changes in the sheet metal
    processes over his time in the trade, all of which create complications
    for panel beaters and spray painters and all of which require skills
    updating. I seem to recall you have never done a *trade* as a panel
    beater or a spray painter nor have you ever worked in that industry so
    you would never have done skills updating courses either. All you've
    ever done was a *hobby course* in panel beating and spray painting at
    Richmond TAFE, a course designed around enabling a hobby car restorer to
    work on their own cars.

    Anyway, galvanic hot dipping proves that bullshit of yours wrong. It
    only became generally used from the mid 90s so a *BIG* change a mere 30
    years ago.

    protection. Cars today are very well sealed against road grime and
    moisture compared to years ago with all kinds of inner splash shields, seals, deflectors, under body trays, you name it. All of it designed to

    that will do oil.

    Car bodies are corrosion dipped at the factory during their manufacture.

    It's what they are dipped into that makes the greatest difference - ie.
    hot galvanic dipping.

    I am reminded of the Nissan UrVan bodies that were too tall for a
    dipping vat designed for cars. Those dipped vehicles rusted like hell
    just above the dip "waterline" which was an inch or three under the rain gutter. Real quality products, those Nissans! LOL

    An oil spray starts with a cleaning, followed by the oil. And it's a

    https://www.finalcoat.com/assets/lab_tests/CC_Tech.pdf

    And "Final Coat" have had their device's experimental results
    published in scientific papers (the same testing that the Canadian
    regulator also accepted):
    https://www.finalcoat.com/news.html

    But details of a test done without any financial motivation for its
    success would be very interesting.

    I took a quick look at the ITS report pdf. It says the test was done by immersing the panel in a saline solution.

    My friend was able to get some painted panels from an engineer who
    worked at Ford and was interested in the test. He then hooked up one of
    the devices (he borrowed it from someone who owned one) and sprayed the panels with a periodic spray of saline solution. I think the full test
    ran for 6 months.

    The idea behind the spray was that it would more closely approximate
    normal usage on a car, and not marine usage, where things like
    sacrificial anodes for corrosion protection are common.

    The painted panels started corroding within a couple of months and were pretty damaged by the end of the test. A lot of the corrosion started at
    the edges where the metal was bare, but there was corrosion that started
    in the middle of the panels as well. I figured that the edge corrosion
    would be similar to what would happen to a surface with a scratch in the paint.

    He did have some panels in another enclosure that were not connected to
    one of the devices. There wasn't much, if any difference between the
    sets of panels. They all rusted.

    The test was done in the late '80s, so I'd expect that coatings
    technology has greatly improved since then, plus I know that at least
    some (all?) of the car makers now use galvanized steel for body
    parts. There's possibly less need for one of these devices now than
    there was.

    I'm not telling anyone what to buy or not buy, but I know that for
    myself I wouldn't spend the money on these gadgets. I'd rather put that
    money into washing my car to try to clean the salt off.

    I think my friend wound up having more fun building the test rigs than anything else. Running the tests themselves was about as fun as watching grass grow. :-)

    BTW, I'm not disputing the electrochemistry that's the basis of these devices. I'm just not convinced that it applies to these devices in the
    real world on cars being driven on roads, particularly in areas where
    they're exposed to salt.


    Another aspect to these devices is their power consumption, to work they
    would need to be on 24/7, if a vehicle was parked for long periods of
    time I'd expect that its battery would be drained fairly quickly even
    more so on modern cars that already have power hungry devices such as
    security systems consuming power all the time.
    To prevent battery drain the devices would need to be turned off when
    the car wasn't running which must reduce the possibility of it working
    even further.

    A friend of mine tested this in the lab when I was in college. The

    He wrote a paper on it for the class he was in, but I don't think it was >>> ever published since it just debunked some junk science and didn't
    actually represent any new and valuable research in terms of chemistry.

    That's a shame, it would have been interesting to compare his
    device and test rig with the successful Canadian lab tests:
    https://www.autosaverobd.com/wp-content/uploads/2023/02/ITS-REPORT-015-05015-4-_3-15-2007_.pdf
    https://www.finalcoat.com/assets/lab_tests/CC_Tech.pdf

    And "Final Coat" have had their device's experimental results
    published in scientific papers (the same testing that the Canadian
    regulator also accepted):
    https://www.finalcoat.com/news.html

    But details of a test done without any financial motivation for its
    success would be very interesting.

    I took a quick look at the ITS report pdf. It says the test was done by immersing the panel in a saline solution.

    My friend was able to get some painted panels from an engineer who
    worked at Ford and was interested in the test. He then hooked up one of
    the devices (he borrowed it from someone who owned one) and sprayed the panels with a periodic spray of saline solution. I think the full test
    ran for 6 months.

    The idea behind the spray was that it would more closely approximate
    normal usage on a car, and not marine usage, where things like
    sacrificial anodes for corrosion protection are common.

    That's how the other test in the second link was performed
    (described from PDF page 7). However the spray there was continuous
    rather than periodic, so your friend's test could have been more
    realistic in that regard.

    The painted panels started corroding within a couple of months and were pretty damaged by the end of the test. A lot of the corrosion started at
    the edges where the metal was bare, but there was corrosion that started
    in the middle of the panels as well. I figured that the edge corrosion
    would be similar to what would happen to a surface with a scratch in the paint.

    I'm not sure about that, and it would depend then on how the panels
    were cut.

    He did have some panels in another enclosure that were not connected to
    one of the devices. There wasn't much, if any difference between the
    sets of panels. They all rusted.

    The test was done in the late '80s, so I'd expect that coatings
    technology has greatly improved since then, plus I know that at least
    some (all?) of the car makers now use galvanized steel for body
    parts. There's possibly less need for one of these devices now than
    there was.

    My interest is in protecting older vehicles, from the 80s and 90s.

    I'm not telling anyone what to buy or not buy, but I know that for
    myself I wouldn't spend the money on these gadgets. I'd rather put that
    money into washing my car to try to clean the salt off.

    I think my friend wound up having more fun building the test rigs than anything else. Running the tests themselves was about as fun as watching grass grow. :-)

    The awkward part for doing tests myself seems to be cheaply
    aquiring car body panels to test it on. I could fall back on just
    trying it on cheap galvanised sheet metal and assuming the results
    would relate to automotive panels, but much of the documentation
    suggests that the glvanising plays an important role in how the
    devices work, and looking around at all the galvanised steel
    rusting at completely different rates around my property (some
    probably on the vehicles that I want to protect) demonstrates that
    it varies a lot in quality.

    BTW, I'm not disputing the electrochemistry that's the basis of these devices. I'm just not convinced that it applies to these devices in the
    real world on cars being driven on roads, particularly in areas where
    they're exposed to salt.

    Salt isn't actually a factor for me in (non-coastal) Australia,
    which is why this test in a humidity chamber is more relevent: https://www.finalcoat.com/assets/lab_tests/Smithers.pdf

    However it's unclear why that wasn't sufficient for that company
    to fend off the Canadian regulators who required they do that other
    test later before allowing sales to resume. Perhaps there was an
    issue with the independence of the lab? It looks like the only way
    to be sure is to try it myself.

    Or just plug it into a top-up charger when parked at home. A small
    price to pay if they worked. In fact the Jag needs that anyway if
    parked for many weeks because its electronics already pull too much
    current while it's parked (a known issue with that model).

    All the *power hungry devices* on modern cars should go into *sleep
    mode* when the car is turned off, locked and unattended. In sleep mode, vehicle subsystems are switched off or to an inactive state to prevent
    any parasitic draw on the battery. If the vehicle is inactive for,
    typically, 2 weeks and/or the battery falls below 9.5 Volts, the vehicle shifts into *deep sleep mode*. For some vehicles (Ford), the only way to
    exit deep sleep mode is to start the engine with the key, remote start
    being disabled. Darren's Ranger will have this facility.

    To prevent battery drain the devices would need to be turned off when
    the car wasn't running which must reduce the possibility of it working
    even further.

    All done *automatically* Daryl. The system controlling parasitic draws
    has been in cars for, quite literally, *decades*. Please try to keep up.

    So, if you park your car immersed in a pool of salt water it works. How
    does that relate to a car parked in air?

    The point being made is that for the device to stop rust it would have

    device means that the car isn't protected when parked up for any length

    Exactly but that's a bit too complicated for Xeno to figure out, a rust control device would need to be always on, only way to prevent the cars battery going flat is to drive it often or to attach a charger whenever
    the car is parked.

    Exactly but that's a bit too complicated for Xeno to figure out, a rust control device would need to be always on, only way to prevent the cars battery going flat is to drive it often or to attach a charger whenever
    the car is parked.

    Exactly, and this is yet *another* example of the "teacher" being about
    as clueless as you can possibly be.

    Ah Darren, you are the poster boy for cluelessness in this forum!

    Nothing astonishes Noddy so much as common sense and plain dealing.

    Give it up Fraudster. Your opinions carry as much weight as Peter
    Duttons' head has hair.

    They only draw less than 1 Ma of current. Some claim as little as
    1/3 of a ma (most of that from the tiny LED that indicates it is on, I

    That was my understanding, very little current draw.

    would imagine) There does not need to be any current draw to provide a
    difference of potential between 2 components, and it is that potential

    Good point.

    As a capacitor, I expect the car body is very 'leaky', so keeping
    it charged would require a constant current to offset losses. This
    may be why the pulsed signals are preferred by at least the better
    documented designs. The first concern by the Canadian regulators
    seems to have been whether there was a capacitance effect at all
    or simply a dead short, hence a lot of test documention is about
    showing that the charge can be measured all over the surface of the
    vehicle's paint.

    difference (basically voltage) that is supposed to prevent corrosion

    I was under the impression some of them mentioned a *frequency* of some
    sort but, as I have said previously, I have seen nothing in the way of detailed documentation on how they operate.

    I already posted links to papers which describe how at least one
    device uses short pulses to charge then discharge the capacitance.
    There's more detail in the patent for an earlier device from that
    manufacturer:
    https://patents.google.com/patent/US5407549A/

    It uses inductors in order to most efficiently generate
    current-limited electrical pulses. For my static experiment I'll
    be lazy and just limit the current with resistors in my DIY
    equivalent circuit, since for that I can use mains power.
