    What is the best paint for aluminum? I would like one that is thick and will be used over just the trim and not the hull.

    I've been using krylon's new spray paint on my stuff for a while. Looks pretty good, but not as durable as a 2 part paint.

    Make sure you prime it with a self etching primer before painting.
    At the boatyard, we used to use Awlgrip on everything.
    Just different prepping for different applications.

    I have no idea the brand we used over there.
    But just ask for any self etching primer over at the supplier.
    I believe we use SEM at the shop?

    in my line of work, which is aircraft, we use an etching epoxy primer but small parts or touch up areas we use the green zinc chromate.

    We used the green zinc chromate on small brackets as well.

    And I believe Awlgrip etching primer on the bigger stuff, although we only did something big on one of the boats, and I didn't even spray it.
    All I sprayed were the actual hull caps and the rutters in Awlgrip.
