If it does everything it claims it’s a great product. But….its hard to work with. It starts getting hard after about 5 minutes of opening it. Cut your hole large to help with the squeezing.

I love this stuff. I wouldn’t use anything but it. It’s great quality. The smell isn’t strong. It’s not messy. And is great for sealing up lights and stuff to the hull.

I used the adhesive to seal a clear plastic tubing to a concrete fountain, supporting water flow through the tube and not letting water leak between the tubing and concrete. At 2 months there is no leak

This stuff worked perfect. I had a pin hole in my pool and as the water was spraying out I put this on my finger pressed it over the hole and it stoooed🤩 It holds up phenomenally!

We used this sealant to seal some cracks in our Honda that were causing water leaks. This product was easy to apply and sealed the cracked that was causing the water leak. I would recommend this sealant as a cheap and easy solution for water leaks in cars.

This product, works completely as advertised. Nothing adheres any better, above or below the Waterline.My only complaint (why I gave value for money only 4 stars) is that they don't make it in any smaller quantities. Often times, you just don't need 3 fl ozs. And once you open the tube, and the air hits the end, you can't put the genie back in the bottle. It's all going to harden, used on the project, or left in the tube :-(
