for your curbed wheels.

if you paint the wheels yourself, make sure you spend at least 50% of your time cleaning the wheels in preparation of the painting. And paint in a clean room that is well ventilated without dust blowing around.
Tower Paint will sell you VIN# matched paint in a can if you want to paint interior bits as well.
