Hi this is my first restoration project and I have many questions. I wanted a aluminum hull so it would last without fiberglass problems. However my old fiberglass boat the floor was sealed to the side of the boat so there was no crack between floor and hull. I dont want carpet back in this boat so if I use bed liner how can the crack between hull and floor be sealed?? Is this a price you pay for aluminum boats? Also can I put the bed liner straight to the plyboard or do I have to fiberglass it first? ---Thanks Alan
