I did mines with ceramic caliper paint( forgot the brand) it's made for the calipers heat and doesn't attract dust. I cleaned my rotors with a brush and soap or caliper cleaner and I gave it a quick sand down with fine grain sand paper. Cover everything that shouldn't be painted and then give it soft coats of paint, let it dry for 5 min and continue again several coats with dry time in between. I did 5 coats. Once your happy how it looks your done.
