A fast curing, one-part polyurethane that chemically reacts with moisture to deliver strong, flexible bonds to wood, gelcoat and fiberglass. It forms watertight, weather-resistant seals on joints and boat hardware above and below the waterline. In addition, its flexibility allows for dissipation of stress caused by shock, vibration, swelling or shrinking. 3M 4200 is designed to allow disassembly of wood and fiberglass parts bonded together. If a permanent bond is desired, use 3M 5200 Adhesive/Sealant.
