I used the cool seal that bud talked about in his post in 2006. A friend of mine bought a new motorhome with a fiberglass roof and gave me a gallon of the coating and a gallon of the primer. It looked good for about four years and then it started to peel off in small sections. I believe it is some kind of acrylic coating. These coatings are cheap enough to apply every six years or so to keep the roof looking white and reflecting the sun's heat. I would just clean your roof really well with bleach ,a scrub brush and a pressure washer to remove all of the old caulking and mold, then wipe the areas to be re-caulked with a solvent. When the roof is clean and re-caulk I then would apply this acrylic coating and use two coats , I only had enough for one coat.
