3M 4200 Fast Cure Polyurethane/Adhesive Sealant

Cures fast and forms a watertight seal between joints and hardware

One-part, all-purpose sealant chemically reacts with moisture and forms flexible, watertight, weather-resistant seals on joints and hardware. Can be used above or below the waterline; approximately half the strength of 3M's 5200, which allows for eventual dissasembly of parts. Note: Can be softened by some teak cleaners and sealers and is not recommended for sealing teak decks.
