i painted my stock rims back in january. turned out nice, but already see a few knicks of paint out from normal rocks and debris, but still look good!
i used dupli-color high performance wheel coating. all metalic. also used dupli color primer and clear coat. did 2-3 coats of primer............ALSO sanded the wheels down not completely, but to get a rough surface
2-3 coats of paint
then topped it off with 3 light coats of clear coat, and your good to go!
