Works great
Would Recommend[This review was collected as part of a promotion.] I was pretty skeptical about this at first. With all the hype and commercials I decided to give it a try. Listen I get it but this stuff is amazing. I use it for everything now! From cracks, nail holes in the wall, bathroom to seal the tub around the edges I mean everything! It holds like nothing else I've ever used, easy clean up, mess free, no smell I mean it just works! Don't take my word for it just try it you won't be disappointed!

Would RecommendIt poured out thick, like heavy paint, and rolled on smooth. It also went further than advertised. Looks great, and the leaks through the fabric roof stopped.
