FLEX PASTE Super Thick Black Rubber Paste - 1 lb.

Introducing the newest addition to the Flex Seal Family of products. Flex Paste is a super thick rubberized paste that clings to the surface and instantly fills large gaps, cracks and holes. Once dry, Flex Paste turns into a strong, flexible, watertight, rubberized coating that seals out air, water and moisture. Our super thick formula will not wash away, and will even cure underwater.
