How to paint an aluminum boat?

I have refinished a couple of pearly monarchs in the past year. I've decided that the best paint to use for this job would be paint used in the auto refinishing systems 1st sanding with 240 grit paper then cleaning with a mild solvent degreaser ensuring surface is dust free 2nd apply 1 - 2 coats of two-pack etch primmer leave for about 4-5 hours then lightly rub with a grey scotchbrite repeat the degreasing process then its ready to put a top-coat on. I have found that two-pack acrylic paint with a plastisizer additive works best the additive give a very durable surface and reduces chips and scrapes. O hope this has been helpful.How to paint an aluminum boat?

You'll need an etching chemical or a self-etching primer. Aluminum is notorious for being difficult to stick finishes to.





For example, I'll scrub the boat with Alumaprep using a scotchbrite pad. Next I'll brush on Alodine, and rinse. Next put on 3-4 coats of Interprotect 2000/2001E. This is an epoxy-based barrier coat for fiberglass and a primer for metals as well. Then you can apply your finish as you like. If you're painting the bottom for salt-water use, go with something like Trilux 33 or Alumaprotect. You'll need 3-4 coats again.
Just like anything else. Prep the metal by sanding and then spray it.
