i've done powder coat on my wheels before, but never paint, which i've seen some shops offer that seemed to yield great results.
has anyone ever compared powder coating wheels vs. painting the wheels? i'm assuming paint offers more color variety & custom features, but not sure what other advantages/disadvantages it has vs. powder coat.
Powder coating is much better as far as wear and will outlast paint. As far as color choice if you are dealing with a good shop you can get a limitless array of colors. Just like paint it is a matter of pigment. When I powder coated mine I got the dupont # for Porsche GT/Green and they were able to correctly match it. My wife has a limited edition Boxster that is the GT/Orange. Funny Porsche charges $5k for this color and the Dupont color code is what the DPS calls "Safety Orange" go figure. But my wifes car gets a hell of a lot more ooh's and aah's than my Cayman does. But then again she is a tall blond driving a Porsche.
Hi Guys. The only caution I would add regarding powder-coating of wheels is that the temperatures involved could alter the strength/hardness/temper of heat treated wheels. I would mainly be concerned with forged lightweight high-strength wheels. The temperature at which the typical (6061-T6) forged wheel would be affected starts at somewhere around 400F. Effects would not be detrimental, but if I had very expensive forged wheels I would take care to keep the temps as low as practical. I think there may be some powders that cure at a bit lower temps than others, and some may just be controlling of the oven with care. I would not be concerned with heavier wheels (i.e. most cast ones) as they are probably not heat treated or stressed very highly. I do not have the exact specifics on this, having not been through it, but I did want to communicate the basics. I do agree powder-coating is more durable than paint, having used it on several other projects (chassis, etc.). Regards, Jeff.
Jeff G brought up a good point but the temp is not an issue when done correctly. Weight is usually the concern and is not an issue either since there are ceramics out there on the cutting edge of technology. The cost is anywhere from $50 to $300 as color and ceramic type vary. You want to worry about wheel integrity check out how they are repaired.
I know this is an old string, but you guys that have done powder coats, how did you go about locating a reputable vendor to trust with your wheels? I don't have the slightest clue, other than checking with my local Porsche dealers...any other ideas?
Powder coat has lots of pros. It hides minor blemishes and is very durable. If for a track car where you check for cracks regularily it can hide them.
Paint has its pros too. Easier color matching and can be durable as well, it is all in the prep.
One piece wheels powder coat very easily. But you should mask/prevent the powder coat from getting into the lug bolt/nut seat area. The simplest way to do this is to get a nut, bolt and washer. Get a washer that is large enough to cover the seat area and bolt it into the wheel. Also mask carefully the hub bore area and the hub pad (the part that sits against your hub) with the proper high heat tape. Then all should be good.

Thanks Jeff - great advice. I'm planning to powder coat my OEM 17's (semi-gloss black) and wouldn't have thought of that.
Surely the painted wheels that Porsche offer from stock (quite expensive option) will be as well prepared as the standard silver?
My preferred local dealer told me that they'd paint the rims and put a powder coat of clear over it - if they can truly do a clear powder coat, I've no reason to think that they'd be any less resilient.
With that said, they were looking for about $250 per wheel. Yeah,...good luck getting me to sign up for that!
