Marine Adhesive Sealant - 4200 Fast Cure, Black 10 oz. Cart.

This is a fast curing, one-part, polyurethane adhesive sealant that creates strong, flexible, removable bonds.
If a permanent bond is desired, use 3M 5200 or Fast Cure 5200.

Fast Cure 4200 chemically reacts with moisture in the air to bond to wood, gelcoat and fiberglass.
It forms watertight, weather-resistant seals on joints and boat hardware, above and below the waterline.
