I have a 1989 flat bottom crappie boat that is in need of a paint job. the paint on it now is dull and its got a few rough spots on it. i am going to put new seats and line the whole inside with carpet so im not worried about painting the inside just the bottom and sides. my quetion is can i rough sand the old paint and clean it up and primer and paint with any kind of paint or do i need to by some kind of special paint? any input on this would be appreciated,thanks
