Spray Rubber Sealant Coating, 14-oz, Black (6 Pack)

I used Flex Seal on my boat and was genuinely impressed with the results. It sealed up small cracks and leaks quickly and effectively, even in areas exposed to moisture and movement. The application was easy—just shake and spray—and it formed a durable, rubberized coating that held strong. What stood out most was its flexibility and waterproof performance. It adhered well to the surface, and after curing, it created a solid barrier that’s still holding up through weather, spray, and regular use. I’ve tried other marine sealants before, but Flex Seal delivered fast results without a mess. Highly recommend it for boaters needing a quick, reliable seal for minor repairs. Fantastic product.

Easy to use and Fixed all the small leaking spots on the roof. Will buy again.

as advertised

Easy to use and covers quickly. Great for places you can’t seal another way.

Great deal, on flex seal

The flex seal spray is ineffective in sealing gaps even as small as 1/32 inches! May new need to spray multiple times waiting for the previous sprayed area to dry out before applying another spray layer. The spray is too think to effectively seal the gap in one process sequence. The liquid formulation in a can is more viscous and more efficient in sealing gaps and tiny holes!

Does what it say it will do

Spray is weak,not very dependable
