Silicone Rubber
Marine-Grade Sealant
This is an all-purpose, 100% high-quality silicone sealant that is ideal for marine use. It has superior flexibility and adhesion to fiberglass, plastic, metal and wood. It retains flexibilty and tensile strength even after years of exposure. It's tack-free in 30 minutes or less, and fully-cured in 24 hours. Acid-free cure will not corrode metal. (Note: All curing times are subject to atmospheric conditions.)
