I painted my calipers over a year ago using the Duplicolor Caliper Kit. It consists of a can of spray on cleaner, a can of paint, mixing stick, and a brush. I removed my calipers because I didn't want to mask off the rotors, etc., and I needed to bleed the brakes anyway.
I planned on applying clear coat after applying the decals and bought a can of clear (I don't remember which brand). I applied a couple of coats of clear with no problems, and then applied one coat too many which caused a cracking look to the paint. I didn't apply the clear to the other 3 calipers. The 3 calipers without the clear still look great. The one with clear still looks acceptable, but not nearly as good as the other 3. Just don't apply to much clear too quickly and you should be fine.
