Ron,I agree that BTS is a good product for wipedown, but it does not do the same thing on fiberglass that Protec Sealant does. BTS is not a sealant or a wax, and does not bond to the gelcoat the way ProTec does. I use both products, and like them both, but BTS will not PROTEC and shine a glass hull like the sealant does.I will also say this–BTS is the BEST stuff Ive ever found for combating mildew on vinyl seats. I had a horrirble issue with mildew on pontoon boat seats. NO more. Spray them down with BTS, and that problem is over.Mike Whitten
