This stuff is an amazing and cheap way to fix a leak of any kind or size!!! I have not actually used this roll. But I have used Flex Tape in the past, and it is great! Easy to use, works really well to stop leaks. However, I'm not sure if it will work under pressure (i.e. pressurized tanks, etc.), never tried that. The only bad thing I can say about it is that it's awfully expensive, still cheaper than a plumber, though!

a cracked shower pan,

I had a shower pan that was cracked and caulked but leaked anyway. it was bad. to replace it would have cost hundreds of dollars and a lot of work and if i had to hire it out it would have been a thousand dollars or more. I took sheet metal and used flex paste adhesive/glue. i put a patch over the cracked area. after it dried i used seal tape, and then took the flex seal spray and went over everything. i used almond and it matched up OK. so far it has been a few months and it looks great and most of all i don't feel like I'm going to fall through and now it does not leak. I am very satisfied with flex seal products.

Greenhouse Panels

Very happy with the results. Sealed the greenhouse panels since they were blown out in a coastal storm. Since then have had high winds and they did not budge. Can't really cut a straight straight line with the 8" width roll as I made 2" long strips and it is rather gummy material. But no matter, I was looking for functionality rather than esthetics. Also, the large roll was much more economical for the project instead of purchasing 2" wide rolls
