Best product
I would give 5 stars for the product but having it in a tin can, it’s hard to get it out before it starts to dry (about15 minutes).The spray can is easier to use. I have used it on a lead liner around the chimney on the roof, (as water started to come in when it rained), and having box gutters, i used the whole can in the holes and after it dried, finished it with a spray can just in case i missed anything.

Not as easy to apply as I would have liked but if my garage doesn’t flood inthe spring it’s worth it

Does not work under water as stated! Does not seal up the best. Needs a better airtight method!
Does not work under water as stated! Stays on putty knife and will not spread under water. Just globs and falls to bottom of pool! Great product for sealing around things. Was not sealed the best and had to waste quite a big ring of paste as they had not air sealed it the best. Also seemed to not be that full of a pail. Used it to patch the walls of my above ground pool around jet and skimmer. Plan on using to patch the liner inside in 2 places as well. Hopefully it does not harden before I can use the rest. I sealed it as shown and hope it does work.

Solid as a brick. No good. Don't buy
Crap. I've used flex paste before and was very happy with the results. This crap from Amazon was dried out and solid as a brick. I initiated a replacement through Amazon and the replacement was also a brick and was obviously tried by a previous customer. Not happy. Gonna try Gorrila paste. So far Gorilla is not a brick. Good start
