I am facing my first spring as a sailboat owner (1966 Oday Mariner 19'). The bottom of the boat needs some work, as there are many layers of flaking bottom paint. I am interested in advice from all you veterans regarding the work necessary specifically on the bottom paint of a fiberglass sailboat. How much of the existing paint should I sand off; until I get to a smooth layer, or should I uniformly remove the multiple layers of blistered and flaking paint? Do you clean up the blistered areas and use a filler material in the resulting depression, or just paint over it and don't worry about the uneveness of the surface? What is the best kind of power sander to get? Most folks that I have asked recommend a random orbit sander. Any makes and models that you like? I have heard many opinions regarding the choice of bottom paint. I moor the boat for the entire season, and therefore am interested in an anti-fouling formula. The former owner used a "weeping" paint that did not accumulate much growth. I have read that you should use the same or similar paint to cover an existing treatment. I have the boat up on a wood cradle in my yard at home. How do you deal with the areas of the hull that are covered by the pads of the cradle? Anyone know of a website that provides such information ? Any advice is appreciated! Thanks, Scott
