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. 4200 delivers flexible bonds with good adhesion to wood, fiberglass, gelcoat, certain plastics, and metals. It is paintable and sandable, and forms watertight, weather-resistant seals on joints and boat hardware above or below the waterline.
