    I like all Gorilla products but this was unusable because I have no caulk gun. Waste of money.

    Well sink does not leak around seal any more! Tried other brand and my bead would just pull off after a few loads of dishes. Decided to take others advice and go with Gorilla. Very happy with the application and sealing the sink. But a little concerned on the length of viability. After a few months Im seeing some evidence of my bead starting to peal back. Time will tell.

    Greater than one week

    We had a shower installed and from the start it leaked at the base of the door. The guy came back and twice to seal it with professional proprietary caulk. After a little over a year it started leaking again. I called the company and they said caulking wasnt covered under the life time warranty. They also had no one in the area anymore so they would contact another person. He never showed up. So I bought and used this product from amazon, located the leak. Stripped and cleaned the area applied this product and by the next evening we took two showers and no leaks. Love it.

    Really disappointing. I had to fight really hard to get it out of the container and then it exploded. Not sure if it’s even going to work, but I certainly tried.

    I like the Gorilla brand. Is always perfect for what I need it for. I used this to seal my sunroof, hasnt leaked yet. To repair the loop on my Bluetooth before it broke and cracked the wires. Its pliable so it doesnt hurt my ear, actually pretty soft. Doesnt look pretty, but it works.

    This item will do what I need it to do. I am using it to attach a strip on my walk-in-tub to keep water in and not leaking.
