AKL, I am in the middle of prepping 2 sets of wheels and will be refinishing them myself. Prior to doing so I looked into having them done for me and what methods to pursue, one of the things I had learned is that unless they are forged wheels (most OEM Porsche wheels are not) having them powder coated is not recommended.
Apparently the potential downside is that it if the heat employed in the powder coating process is too high and it will compromise the structural integrity of the wheel; the heat could damage the casting. I'm not one to usually give credence to darts thrown from afar, it's just that many people who are smarter than me (Including Damon at The Tire Rack) noted the above. Good Luck........
