I'm a pretty good artist but just a very BASIC mechanic...

I'm considering painting my brake calipers red on my 986 but I really don't want to remove them in fear of running into the possibility of messing up some of the braking components up. (I've done brake jobs on VWs long ago but that was long ago). I may just remove the wheels and hand paint/spray them myself...has anyone ever done them by hand? Any recommendations? Any advice?
