    Was just as advertised. Was easy to apply and looked good. I mainly chose this one because it had the shortest curing time. Plus Gorilla brand had a pretty good reputation. Pleased with the outcome.

    I was surprised at how strong of a bond this adhesive/sealant makes and it makes no less strong a bond even underwater. This is new technology by Gorilla. And Amazon has the best price.

    I moved into a new house and the window sill by my bed was coming apart from the wall. there was a large gap across (its actually 2 windows right next to each other). I bought a different brand of caulk first, which worked well but I needed more than one tube so I bought this one. This one had a very strong chemical smell. I kept the windows open and it took about 2 days to clear the smell out. The previous one had a smell but it was very faint and went away as soon as I was done. However the caulk worked perfectly so still 5 stars.

    Takes long time to cure and remains tacky. Expensive.

    Ya gotta use it all at once. There is no real cap to secure it if you dont finish it in one application. Typically you remove the applicator tip, clean it, put it aside, and then put the regular cap on to keep it from either drying out or solidifying. There was no cap to close the dispenser.

    Have a cap over a truck bed that was aging and now leaking around one window. Several tubes later Im leak free. Any job like this a couple cheap putty tools makes it easier

    This product doesnt come with any kind of a cap, so there is no way to prevent the caulk from drying out. I suppose you can say that the caulk itself forms a cap, and the next time you use it just pick off the dried part? I have not used it for a second time yet so Im not sure how easy it will be to remove the dried part.

    I did mess up the first tube. Did similar to first tube that exploded but when gel wouldn’t come out I tried twisting the top I cut. There is an inner seal! Poked some holes in and reattached tip. Hey it works. Seam I need is bigger but nothing comes out the back!!!! If you read and want to charge you may. Don’t think original was defective. Uses error!
