its easy, i painted my stockers, i know lots of people have its really easy. just prep the area before you paint them and you will be fine. (sand, clean, prime, paint, clear) IIRC, the wheel paint at autozone and checker is around $5-6 a can and it works great.
^ ditto. it is very easy to do it yourself. i painted mine his past fall. just rough em up with some sand paper. tape off the tires, and spray away. i did 2 coats of gold, and 2 coats of clear on mine. no primer (wheels had been pre painted) after 3-4 months only a few minor chips, not even noticeable.
