I wanted to paint the front disc brakes on a car that I am working on. I got the calipers cleaned up good but the cylinders were a problem because they are new with nickel plating on them. I have had good luck etching nickel plated bolt heads with phosphoric acid so that paint would stick so that is how I decided to do these cylinders. Two of them darkened up pretty quickly but I had to really work at the other two and they still didn't darken like the first two. I rinsed them off with water very aggressively. When I came back to them today I used acetone on them and scrubbed them really well with a toothbrush handling them with latex gloves on. I put on a light coat of the Rustoleum brake paint, and started to get bad fish eyes. I gave it some flash time and put on more coats with more flash time, and finally the fish eyes closed up. I went back after another hour and a half and put a last coat on and they look good now. I hope that it lasts.
