The boat is a 1979 17ft aluminum CrestlinerLots of days in the sun faded the paintIt is currently red and white and I think I will keep it that wayI don\'t need it to look like a show boat or anything, it\'s a fishing boatI really don\'t want to remove all the old paint and get the boat to bare metalSo whats the best way to get this done quickly and sightly more professionally than house paint and a broom?Use a RO (random orbit) sander with a medium grit (150-ish) paper to sand all of the surfaces and give something for some new paint to stick toDon\'t be too aggressive or you\'ll be looking at the aluminum Clean the surface with wax/grease remover (paint prep)When it\'s clean, apply a coat of decent primerThis can be done with a brush, roller, or sprayed onThen apply something LOW gloss (hides any boo-boos better) in your choice of colors to cover the primerShould last for years - but remember, prep is the most important partEDIT: Thanks for the props, tiki - but if you don\'t go all the way down to the aluminum, I\'d save the extra $$ that the zinc chromate primer would cost.Other related question
