I have an old 83' Skeeter Bass boat that I am wanting to repaint. I have the Rustoleum marine paint and primer. I plan on putting in the large amount of prep work required, but I have a few questions about the prep. Most of the areas I want to repaint are a metalflake finish and my question is...do I need to sand all the way through the metal flake before I primer and paint or do I just need to sand it down to a smooth finish? I am not sure if the metal flake would eventually alter the finish or break through. And if any of you have painted a bass boat and have pictures I would love to see them.
