BoatLIFE Silicone Rubber Tube - 2.8 FL. Oz - White

The BoatLIFE Silicone Rubber Tube in white is a premium marine-grade silicone sealant engineered for demanding waterborne environments. Delivered in a 2.8 FL. Oz tube, this all-purpose sealant delivers non-corrosive, non-yellowing performance above and below the waterline—making it the go-to choice for both casual boaters and professional marine technicians protecting hull repairs, seam sealing, and hardware installations from salt spray and UV exposure.

This silicone sealant achieves tack-free cure in 30 minutes or less, with full cure in 24 hours—allowing you to return to the water on your timeline. The formulation will not shrink, crack, or dry out over time, maintaining superior flexibility and adhesion to fiberglass, plastic, metal, and wood even after years of saltwater exposure. The acid-free cure formula prevents corrosion on metal fasteners and hardware, a critical advantage in marine applications where galvanic corrosion can compromise structural integrity. Low odor and mildew-resistant properties further distinguish this product for confined cabin and below-deck work.

Weekend anglers sealing transom corners and fishing platform joints benefit from the flexibility BoatLIFE maintains in temperature swings and UV cycles. Offshore crews and commercial operators rely on this sealant for structural seam work, through-hull penetration sealing, and hardware bedding where traditional caulks would fail. The white color blends seamlessly with gel-coat and painted surfaces, eliminating unsightly discoloration that plagues standard silicones in high-UV environments.
