As far as paint i have used regular rustoleum paint for my last three boats and it is cheap, strong and last great as long as you prep the surface. Also touch ups later are a breeze. Not for 20,000 boats but great for 1000 boats. I used rustoleum topside and cannot tell difference from regular. Also just FYI it takes long time to fully cure especially if humid. I would give it a full week to fully harden.
