Rubber Sealant did not disappoint!

I used this Flex Seal Rubber Sealant Coating spray to dull some areas of cinderblock that would later be covered by a liner for a fish pond. It provided the coverage I was hoping for and the large can lasted longer than I expected it too. It was effective and worked great in this application. I would recommend it! (Note: The product will not have contact with the actual water in the fish pond. It is not okay or suited for that purpose. Product is toxic to fish)

Used this on an aluminum window seal that had pulled away from the house and was letting water trickle in. I drowned the window seal it the clear spray and I'm happy to say that it stopped the leak until we can do a better more permit fix. Its been about a month so far and no issues yet.

Flex Liquid Sealant Coating works great.

Flex Seal Liquid Rubber Sealant Coating did the job I bought it for. It completely sealed the crack/hole that was in my porch. Then I painted it and it shows no sign of the crack or hole. Great sealer and it matches my porch too.
