Stopped the dripping

Thank you for providing the lowest price on Flex Seal. In a house I own, the sink material is connected to the entire countertop, and I'm not ready to replace it, as that would necessitate replacing the countertops as well. However, the sink is very old and has become porous, which is causing it to leak. I need to seal it to stop the leaks.

Sealed back of rug

I bought this to try to salvage a rug that i love. Its an indoor/outdoor type with a rubbery backing, originally. The upper part still looked good but underneath it was crumbling. Whenever the rug was moved, it left a pile of rubber dust. I cleaned the rug well and gave the back about three coats of Flex Seal. The rug is flexible and stays clean now.

Sealed Out Critter Who Damaged SUV Hood Insulation

Obviously everyone who has watched TV has seen this product. I just used it since I noticed a rodent (maybe a squirrel)chewed away the insulation under the hood of my SUV. The fabric was torn and the little nuisance also chewed away at some of the firewall insulation. I used this to seal up all of the damage it caused. I sprayed 2 applications and hopefully this will work. I hope this llttle guy moved out to find a better home for the winter.
