Replacing 3M's Fast Cure 4200, 3M Marine 4000UV performs the same as 4200 but it has superior UV resistance that prevents it from yellowing due to sunlight. It is a polyurethane adhesive sealant that is very similar to 3M Marine Adhesive/Sealant 5200, but that is about half the strength, which allows for disassembly of parts. 4000UV cures to form a firm, rubbery waterproof seal. Its flexibility allows for the dissipation of stress cased by shock, vibration, swelling, or shrinking. Designed for marine applications above and below the waterline, 4000UV bonds with good adhesion to wood, fiberglass, gelcoat, certain plastics, and metals, and is paintable and sandable, Tack free in 2 hours, cures in 24 hours. 3 oz. Tube White.
