LIFE-CALK MARINE SEALANT

Life-Calk polysulfide compound from BoatLife creates a long-lasting, permanently flexible seam that will seal both above and below the waterline. It bonds to fiberglass, wood, metal, glass and itself, and is resistant to teak oil, gasoline and diesel fuel. Life-Calk dries tack-free in one to three days. The sandable sealant can be topcoated with many paints. It can be applied to damp surfaces, even below the waterline, for emergency repairs. Available in white, black, mahogany and teak brown. $16.09 per 3-ounce tube; boatlife.com
