I sure hope it does, got a few cans ready to go. Sorry if this is an old question... I am new to this stuff, and via my research I found that a self etching primer should help the paint stick to aluminum better. Once I am ready to prime my boat, I will scrub it down with a scotch brite and soapy water, then rinse and dry and apply the primer. Then the top coat will be Rustoleum Camouflage paint, in the dark green color. Just wondering if this etch primer is good stuff or not.
