Well I was off today, and my decision for the day was either spend the day painting my calipers, or go trade my 5 month car in on an ST. I think I made the more financially sound choice.
Took most of the day, between disassembly, cleaning, and multiple coats of everything. For the red, I used an actual brush on ceramic caliper paint kit, which dries to a hard and smooth surface. For the brackets, I used gloss black epoxy roll bar/chassis paint for some chip resistance. Did three coats on each part. I think it was worth a good days work.
