Re: To Anti-Foul or not to Anti Foul Paint, That is the Question
most antifouling paint has copper compound additive, very bad for alum hulls. there are special alum-hull antifouling paints; look at West marine site for info. i think salt water accelerates the galvanic interaction too; if you'll be using your boat in salt and pint is conventional copper-based stuff, i might consider stripping and repainting first.
