How to paint a part of aluminum boat?
Answer:
-What kind of paint are you using? Does the manufacturer have a recommended
procedure? If so, you might as well just do as they say.
Personally, I've never painted an aluminum hull, but I painted part of a
mast once, and I think I just sanded it, rubbed it with acetone, then put
on the corrosion inhibitor (zinc chromate, I think?) and then
white polyurethane paint.
-I have had great luck with a Porter Paint urethane fortified enamel, sprayed
on. Sanding and priming your old hull is the most important part tho. Be sure
you get all damaged or loose paint off and prime the bare metal as soon as
possible. I used an etching 2 part primer from the auto body supply. This (and
the urethane paint) are both pretty nasty stuff so use a respirator when you
are shooting it
