BoatLIFE LifeSeal combines marine silicone and polyurethane into a single formula engineered specifically for fiberglass. It cures quickly in the presence of moisture, carries low odor, and forms a permanent watertight bond on joints subject to structural movement — above or below the waterline. Suitable for decks-to-hulls, thru-hull fittings, vinyl ports, windshield glazing, and bedding marine hardware. Bonds to metal, glass, wood, Lexan, and ABS without attacking gel-coat on removal. Not for use on ferro cement hulls, impregnated wood, or oil-soaked materials.
