i used normal automotive paint on mine, juss to get a quick change out of em. if you mask the calipers off correctly, you don't have to worry. very light overspray won't effect braking. side note... i painted my front calipers, and my rear drums. the front calipers have held up perfectly over the past year, but the rear drums look horrible. they got too hot an the paint flaked off. keep that in mind. best bet is high temp engine enamal. good luck
