Bought 16 ft cutter boat, looks like they may of damaged the bottom at one time along both rails. They fiber glassed it looks ok, but don't really want to sink. Can I paint something over it that might help me make sure it stays on the right side of the water? It's just been fiber glassed and left that way. Been told if I let it set in the water fiber glass could come off over time. Ok why did I buy it? Got it for 300.00 boat motor and trailor.
