I recently purchased a 15 year old pontoon. I have pressure washed the decals off and sanded the sides. There are a few bare spots down to the metal siding. Now I'm ready for paint. What do you recommend for paint? I've read alot about Rustoleum enamel, Rustoleum Marine, and marine paint. Also, what should I use for primer? Roll or spray? Looking for a lasting look without the expense. Any help would be great!
