Re: type of paint on aluminum boat
I painted a 21ft aluminum boat and did not strip all the paint off. I sanded the whole boat with 150 grit paper to knock down any imperfections. I them sprayed the boat with rustoluem aluminum primer. Then i used rustoleum professional paint, and i wet sanded in between each coat. the boat turned out great. Has a real nice deep shine to it.
If it were me, I would not try to strip it all off. I would sand, prime, and paint over top of it.
