I have a 97 four winns horizon that the previous owner painted the bottom of the hull. He said it was supposed to keep mold and mildew from forming. It is kind of rough in texture and actually starting to fade off in places. It looks terrible. Im sure it probably also causes a lot of drag in the water. What is the best way to remove this? Or would you recommend just painting over it? The guy could have at least picked a better color. Its hideous right now.
