I painted the calipers on my Camaro with caliper paint I bought at Advanced Auto. Probably not the best kit, but it came out o.k. Mine wasn't spray on, it was brush on. Which I didn't care for as I could seem to get all of the brush strokes out of the paint. When it cured it looked better but once up close you could somewhat see it. Was fun to try and do once, won't ever do it again.

Yours came out very nice.
