3M 4200 Fast Cure is a one-part general purpose polyurethane sealant with good adhesion to wood, fiberglass, gelcoat, plastic, and metal. When cured, 4200 forms watertight, weather-resistant seals on joints and boat hardware above or below the waterline.
4200 FC (fast cure) is ideal for hardware and bedding applications. It is paintable and sandable. While 3M 5200 sealant results in permanent bonds, 4200 has approximately half the strength, making it a good choice for applications where the bond may need to be broken in the future such as replacing hardware.
