My GSXR front and B4 rear wheels are currently at the powdercoater,getting a fresh dusting of white.
Its pretty tough stuff,I had my RX-7's rollcage done a couple years ago,and its not easy to ding or scratch.Clean up is super easy since powdercoat is smooth,like laquer.Keeping the brake dust off my white wheels should be a breeze now.
PC is thicker than anodizing or most paints,and its quite hard,so there would likely be some damage left behind if you tried to grind it away for polishing a portion of the wheel,like the lip.If your gonna strip it all away,then media blasting is probably the best method.Thats how PC companies prep parts before the process.
