Flex Tape is the original super strong, waterproof tape engineered to patch, bond, seal and repair virtually anything. Its thick, flexible, rubberized backing conforms to any shape or object, creating a bond that strengthens with time and pressure. Unlike standard tapes, Flex Tape's triple-thick formula instantly stops the toughest leaks by virtually welding itself to the surface. It seals out water, air, and moisture effectively, making it ideal for cars, boats, RVs, and home repairs. This 4" x 5' roll delivers reliable performance across multiple surfaces and applications wherever a durable, flexible seal is needed.
