When I wash my car I always use wheel cleaner on the wheels. And apparently my brake calipers didn't like the Meguires wheel cleaner I used cause there was some kind of a reaction with the coating on the calipers and it created these black marks on the calipers and anyways they looked kinda nasty. Not that anyone comes up to my car and says " your calipers look like crap", but I notice. It has been like this since I bought the car and first started using wheel cleaner on it.
SO the other day I picked up a Dupli-Color Caliper paint kit and painted them today. I choose black, thought about red, but to me red calipers signify performance, and my car is defenitly not a performance car. I think they came out good, here are a few before and after pics.
