make sure you clean the calipers very well and put on several coats. I was in a rush, and mine is flaking, but other than that, no complaints.
theres most likely a lot of answers but i used a small can of rustoleum red and brushed it on the calipers on my c5 corvette, never had any problems, just make sure its super clean to start. took about 3 coats.
G2usa.com I used their product on mine and have not had a single problem http://www.cardomain.com/ride/763164
