Alpha 1 has been in fresh water for 15 years. Bought boat for resale but the seasons have changed. Did add bling and sporty feel with 19" SS prop from my parts bin. Prior was 23'! Hull was commercially acid cleaned and I think they got OD. Photo to follow. Current option is to move it to bottom of to do list. Possibles: 1. Spray with WD-40 2. Wire brush and sand down to 100 grit. Carefully mask and spray with Rustoleum Gloss Black. 3. Prep as 2 but spray with self-etching Black from auto body supply store. Stuff sticks but is flat. I have boat detailers and resellers around and I'll check with them.
