Gorilla Ultimate Sealant Window & Door forms a durable, 100% waterproof seal that withstands the sun, rain, and extreme temperatures. This smooth, tack-free hybrid formula outperforms 100% silicone, offering superior flexibility, faster rain-ready time, and a finish that can be painted to match your project. It bonds to wet or dry surfaces and won’t shrink, crack, or discolor, delivering long-lasting protection in exterior joints and exposed areas.
