Powdercoating bad?

I just bought, (and should receive soon) a set of Racing Hart wheels. I am planning on getting the center portion either painted or Powdercoated. Powdercaoting is roughly half the cost and apparently quite a bit more durable. The problem? Powdercoating requires that the wheel get heated to temperatures up to 400F. Since this wheel is a 2 pc unit, will this heating process do anything to the wheel tempering? Will the wheel warp? Are the bolts that hold the wheel together going to be ok? OR if I disassemble the wheel, are there any problems re-assembling the wheels in a very precise manner?

Was that the RH wheels on ebay?

If you only want the center powder coated, then you'll have to disassemble the wheel. From your description, it sounds like it's a 3 piece wheel (you mentioned bolts). Either way, you'll have to disassemble the wheel because the silicone sealant that seals the pieces together will melt in that kind of temperature, not to mention I doubt you'll want the bolts powder coated as well. I would suggest letting a "pro" disassemble/assemble the wheels. The bolts need to be torqued to a specific lb. when assembling, and the sealant must be put on perfectly so that it doesn't leak air.

Any good high end wheel/tire shop should be able to help you with the wheels.

Hope that helps a little

Its actually a 2pc wheel, so maybe there aren't an bolts. I am a complete novice when it comes to wheel stuff, so any help is appreciated.

The wheels actually were not the one's on E-bay. They are a Custom Macufactured set of 18" CP-035R wheels which are currently not available in the US, and will not be introduced here until SEMA of 2002. BUT, I managed to have them build some for me. All it took was an arm, a leg, both eyes, and a kidney, along with 4 months of waiting.

But in any case, If there is some sort of Silicone sealant which is weak to heat, wouldn't that cause problems under severe track use where much of the brake caliper/Rotor heat will be transferred to the wheels?
The operating range of most competition type pads are from 400F-1000F, which would imply that a great deal of it would transfer over to the wheels. How does this affect the wheel integrity?

Also, does heating the wheel to powdercoat it rob it of its temper in any way? Since these wheels are actually not DOT approved for US use, IF one breaks due to some sort of problem I do not think Racing Hart or Dazz Motorsports will help me out.

NONONO Both of you are wrong, I talked to the manufacturer and they INSISTED that they did not use inferior quality Elmer's Glue (Which melts in water). They assured me that they used high quality Rubber Cement, which apparently is quite a bit more water resistant.

Yeah, too bad we can't get that special JDM Rubber Cement. They have higher-performance versions of EVERYTHING in Japan!

Hopefully I don't have a problem with mine. I think my Dymags are 1 piece magnesium wheel, but it may be 2 piece. I plan to have them powdercoated white in a couple weeks and am hoping I don't run into any problems.
