I haven't done it yet. You could take it off or just tape off all around the caliper and do it. Put some news paper in any holes. If you get any paint on the rotors it should just burn right off.its not what others think, i just didnt know if its ok to do or if its bad for the caliber. how did you do it? i want to paint them purple like my tow hook and the lug nuts im gonna order from thenoxus1
