The makers of Flex Seal bring you Flex Shot– the revolutionary super thick rubber sealant that caulks, bonds and seals virtually everything. Flex Shot is the neat and clean way to make repairs with pinpoint accuracy. Flex Shot comes out nice and thick, clinging to any surface, and then turns into a stretchy rubber seal that's virtually indestructible. And because it's so thick, you can fill huge cracks and holes, stopping the toughest leaks instantly! Forget about those bulky caulking guns! Unlike regular caulks that shrink and crack, Flex Shot expands and contracts, making surfaces waterproof. The free extension tube makes even hard-to-reach repairs perfect every time!
