    Not to long ago someone asked about Powder coating wheels for his Renault.
    I am not a fan of powder coating.
    See attached photos as to why.

    That's not good. It reminds me of the time I put that goo into my tyres that's supposed to automatically seal punctures.
    It ate through the paint, and then ate through the steel rims!

    All it needs is a chip then it will rust away on the inside while it looks beautiful on the outside. Eike's G in RSA were prepared for a show many years ago and all his wishbones and other suspension parts were powder coated. Not good! But then only in hindsight because we didn't know better then.

    Our steel security doors are powder coated and look even worse. Total failure of whatever preparation coat they used.

    Better to use a paint brush and decent paint!!

    Funnily enough preparation is the key to the success of all forms of coating.....

    Agree with Kim. Powder coating ,when prepared correctly is very good. If the metal is degreased, etched in phosphoric acid and not touched by any grease bearing substance even human hands, the powder will coat and provide a very durable surface.

    And then you tighten the wheelnuts and crack the powder coating and the oxidisation process starts.

    It will be good for certain applications only. Not where chips or any likely things can happen. The major drawback is that the coating looks perfect while the rust has travelled several millimeters or inches underneath the coating, and you don't know about it.

    I'd suggest that steel wheel is from the 1970's, so it's now 40 plus years old, and like anything else that has been obviously so well cared for, it probably needs a clean up and re-coat.

    i enquired about having some aluminium wheels powder coated, and the guy said pretty much what Frans said. he recommended that it was not a suitable coating for car wheels.

    Looking at the photos again, I'm not even sure it is a powder coated wheel! Just looks like a poorly painted one. Then again, I could be wrong, as the company that makes them is still in business and still powder coats their steel wheels and I seem to remember seeing them on countless 4x4's, not just Renaults!

    I just had a set of rims powder coated. They look unreal and if they last 30 years I probably wont care that much.
    There is a law against doing more than 100kmh...there's no law on how fast you get to 100kmh!!!

    Those rims are at least 70s, if not very early 70s. I should know, I owned them before Johan, and before me by more than one step they belonged to an R8 called Daktari, raced, rallied etc by Mike Marshall.However, I would still be very cautious about where the nuts seat, with any coating including paint! Powder coat technology has moved on a lot in 45 years!
    Kim, these wheels were made in NZ by Jolly Wide Wheels, not the company you quoted.

    Also looks like the rims were run with tubes rather than tubeless.
    Dakar raced, rallied...salt pans perhaps??
    Looks like salt water penetration through to inside of rim through valve area.
    As air is available corrosion will continue

    Lesson here anyone running tube tyres should check internal rim corrosion
    Split rim 4WD also applies here

    Don't really think that NZ has too many salt pans, and a very long way to Dakar
    Yes they had tubes, as did most "rally" tyres back then. I would be surprised about salt water too. Just a long time stored in a barn.

    I may be wrong, but the modern alloy wheels fitted to PSA cars appear to be powder coated on the backs - it seems to endure quite well away from harsh environments.

    I've been going through rims out in the back yard and founds lots of 12 special rims (1 was a G) and scrapped most of them because there to rusty to use and non of them had been power coated.

    Fact of life I think......Steel rusts.

    Yes. They were made in the 70s.

    The ROH wheels are still made in Oz. Either that or they were ahead of their time in having a web site back in the 70s! ��
