I have an old 76 fiberglass boat and the sides of the boat a in decent shape but the bottom theres qite a few chips and a patch also spots were it has worn off from going on and off the trailer.Basicly i dont want to re gel coat it but was wondering if there is some kind of sealer, i noticed on a boat i saw he had like a black almost like bed liner sealer type of stuff on the bottom was was wondering what it is. Anyway any help would be great.
