You CAN paint chrome, it has been done many times and by me. Look up the musclecar tv show on spike.com, there is a episode from this year you can watch that shows you how and what to use. I sanded my camaro wheels down with 200 grit then 500 grit, used house of color adhesion promoter, then a etching base primer, base coat, clear coat, wet sand, buff, Done. Its a lot of work, but for saving good rims that are peeling, its saves a ton of money, cost me $250 to make my rims new again. Its been 6 years, not one chip or peel.
