05220 Marine Adhesive Sealant 5200 Fast Cure, White, 3 Oz

3M Marine Adhesive Sealant 5200 is a one-component, moisture-curing polyurethane formulated for permanent bonding and sealing in marine environments. It is engineered to bond wood, gelcoat, and fiberglass while creating a waterproof seal on joints and boat hardware—both above and below the waterline.

This sealant cures to form a firm, rubbery seal that remains flexible, allowing for structural movement. With over 50 years of trusted use throughout the marine industry, 3M 5200 has earned its reputation for durability. It retains its grip even when exposed to constant wave action and performs reliably in both wet and dry marine environments with excellent resistance to weathering and salt water.
