I had my calipers proffesionally sprayed copperhead, with black viper stickers then clearcoated. now they perfectly match the copperhead and black color scheme on my car with a finish as good as the body paint. A&C Performance took care of all this. Calipers looks great. The entire caliper, fittings, tubes, front and back were done.
They deterred me from powdercoated because then the entire caliper assembly would have to be stripped down and seals cannot go into the oven, then it only make sense to use new seals on re assembly. Too much labor and parts costs.
I guess if copperhead was available in high heat spray can I may have saved money and just done that, however they are real nice now.
