BoatLIFE Life-Calk is a permanently flexible marine polysulfide sealant engineered for demanding above- and below-waterline applications. This mahogany-colored cartridge bonds to fiberglass, wood, metal, glass, and itself, curing to a firm rubber seal with strong adhesion and waterproofing. It resists teak oils, gasoline, and diesel fuel, and can be applied to damp surfaces or even underwater for emergency repairs. Once cured, the sealant can be sanded and painted (not compatible with Sikkens, Cetol, Deks, or Olje finishes).
