Sudbury Elastomeric 3 oz (89ml) Sealant Tube - Clear

The Sudbury Elastomeric 3 oz (89ml) Sealant Tube in Clear is a marine-grade, one-part sealant engineered for anglers and boaters who demand reliable hull repairs and waterproof sealing on the water. Whether you're dealing with small cracks in fiberglass, sealing through-hull fittings, or protecting wooden trim from moisture intrusion, this fast-curing sealant delivers the durability you need in variable conditions. Designed to perform in harsh saltwater and freshwater environments, it's an essential repair tool for any tackle box or boat maintenance kit.

This elastomeric formulation skin-dries in just 10 minutes and fully cures within 24 hours, allowing you to get back on the water without lengthy downtime. The sealant maintains superior adhesion and elongation characteristics across a wide temperature range—from -20°F to 120°F—making it reliable whether you're fishing in winter conditions or launching during summer heat. Its one-part composition eliminates mixing errors, while the clear finish remains inconspicuous on light-colored hulls and doesn't require painting over.

Experienced boaters trust the Sudbury Elastomeric tube for permanent repairs to fiberglass, aluminum, and wood surfaces without the brittleness or shrinkage of traditional caulks. The 3 oz size is practical for small-to-medium repairs and travels easily in tackle storage or bilge lockers. Apply directly from the tube using a standard caulk gun for precision application around windows, seams, and deck hardware—it adheres tenaciously to marine substrates and won't crack under flex or vibration.
