Hey everyone, I am new to the website and just thought I would ask for some advice. I just started to rebuild the wooden floor in my old sea nymph. The wood was rotten and the carpet was trashed. It was my grandpas and when he passed away he left it to me. I already removed everything(including the old water filled foam) and got the new marine grade plywood cut to fit. I bought the ss screws and 1 gallon of tuff coat. I am stuck right now.. I dont know if I am suppose to waterproof the wood?, fiberglass it? sand the wood? I made a special 2 hour trip to cabelas to get the tuff coat not knowing i needed the a special primer, i left without it. I even asked the guy and he told me any primer will do.. I dont know if i believe this. I called the tuff coat company and they said I need to use a special 2 part tuff coat primer on the wood. I really dont want to make another trip to get the "tuff coat primer" any advice will be really nice!
