Swift 12 lb. Black All-Purpose Rubberized Paste

The Swift 12 lb. Black All-Purpose Rubberized Paste is a thick, versatile sealing paste designed to cling to surfaces and cure into a strong, flexible, watertight rubber barrier. It can be applied to dry or wet surfaces and even underwater to fill gaps, holes, and cracks, sealing out water, air, and moisture. Formulated for long-lasting performance, this paste will not shrink or wash away after application. Once fully cured, the surface can be painted any color to seamlessly match your surrounding materials, making it ideal for home, automotive, marine, and general repair projects.
