To anyone looking to paint their stock (or aftermarket) calipers a company called Dupli-Color has made a nice kit for painting your calipers.
It includes a can of paint (red in my case) and a spray can of caliper cleaner. The caliper cleaner you just spray on scrub off all of the loose dirt and stuff with a toothbrush or something similar. It also comes with a brush, paint stir stick, and masking tape and recommended instructions. It was really easy to use and paint the calipers.
The only thing I didn't like about it was that the brush gets hardend from the paint and after a while it makes it a little annoying.......other than I have no complaints and the calipers look great. I'll try and take pics tomorrow when the sun is out.
Here are the pics (finally....sorry for the dirtyness)...
This is the rear caliper...

Front caliper...
I got lazy with the masking tape and painted over some areas I shouldn't have.....doens't look too bad...just try to ignore that

I got mine at Advance Auto for about $15. It's definitely one of the cheapest mods I've done to my car....but one of the most time consuming as well. Good stuff though!
