Flex Paste Pfsclrr32 Rubberized Paste, Super-thick, Clear, 26 Oz

Flex Paste is a super thick rubberized paste that you can spread, shape, form and seal virtually everything. It starts out as a thick paste and dries to a strong, flexible, waterproof barrier that can be applied to all types of surfaces to seal out air, water and moisture. It clings to the surface and instantly fills large gaps, cracks and holes. It won't shrink or wash away and can be painted any color. Can be applied on dry or wet surfaces, even underwater.
