I just painted my FMIC yesterday. I first sanded it down with 80 grit with one of those sponge sand blocks. Rinsed it, then let it dry with the leaf blower. Then I hung it up and cleaned it with wax/grease remover (from a rattle can so it would get inside the fins). Then sprayed 4-5 coats using the Eastwood Radiator paint. Let it dry for a couple hours and installed it. Then I redid my piping so I could use some black couplers.
hope you like!
