I am putting all new style switches in my boat and have had new aluminum plates made up. These plates are not painted so I need to find the best way to paint them. I think step one is to prime with zinc primer. I once used a wrinkle finish engine paint on some aluminum parts on my 15'and it lasted a long time in full exposure however I do not think I want to have that aggresive of a texture.

I just did a set for my boat. Took them to a powder coat place and asked them to throw them in with their next batch of flat black. Turned out great. If you do decide to powder coat you might want to shoot with a sand blaster first. Helps the coating stick and adds a sort of matte surface.

George - I just did mine and had the same concerns. A paint store told me that the best thing to paint over AL is water base but all spray paints I could find are oil.
Ended up wiping down the plates with paint thinner, to kind of etch them, and painted with textured rustolium. I think Bigshot did the same thing. Looks great, but only did it this last spring, so not sure how it will hold up.
