Are you thinking all new gel-coat paint job? Before you do, can I make a suggestion? Take a small area anywhere on the boat--perhaps below the water line. Using a buffer and some compound, give it a good going over to remove the obvious oxidation. Then thoroughly, and I mean thoroughly, clean off any residue left by the buffing, and apply a coat of a product called Nyalic. For some reason, it brings back the color of faded fiberglass/paint/gel coat and leaves a very attractive gloss finish.. This might just save you a lot of time and/or money. If it doesn't work for you, let me know and I'll refund your money. I have NO financial relationship with them whatsoever. I just happen to know the people who run the company. Oh, you should know that gasoline removes Nyalic, so don't use it near your filler unless you are religious about not spilling any.
