An extra-thick adhesive layer with a UV-resistant backing seals out water, air, and moisture — and it works even underwater. Service range from -70°F to 200°F means it holds up in cold and hot conditions.

Use it on roofs, RVs, boats, and plumbing to patch holes, cracks, gaps, and tears. It bonds to plastic, metal, aluminum, rubber, wood, vinyl, and glass. At 4 inches wide and 10 feet long, there's plenty for larger repairs.

Just cut, peel, and press into place, then rub the edges firmly. It ranks #1 in Sealing Tape with 2,000+ reviews at 4.3 stars — worth keeping a roll on hand before the next leak.
