I bought some of the "Bug Slide" product as was suggested in a post here last year. It worked great. The best I've found so far. Made the front of the overhang look like new, however for the amount provided it is to expensive for me and I won't be buying it again. I'll just stick with "NU Finish" wax. It worked well on my fiberglass boats that were in the salt water environment. Nice finish, and seems to last ok. This spring I think I'm going to try the Turtle wax bug remover/protector next on the overhang and see what happens.
This "Poli Glow" suggestion looks interesting too, going to check it out.
