Gorilla Waterproof Patch & Seal Liquid Rubber, Black Sealant, 32 Ounce

So far I love this product. I have not had it long enough to determine the durability. It takes a long time to dry but that is to be expected with a material so this viscus.

Great product seals up nicely!!

Awesome working stuff

useful product

I used it on our vinyl swimming pool that had a 3“ x 2“ L shaped slit in it did it as directed worked fine later I found another small hole maybe a quarter inch long in a different place but I've already filled the pool so I tried it, putting it on under the water and It's hasn't leaked yet

It worked really great repairing a Convertible Auto Roof. The onlty thing I will say, is that the Clear did not hold anywhere close to h0w the black held. The black was perfect, the clear did not hold in places

My chimney cap was bowed in and held water. When installed, they had an unknown sealant. The gorilla bonded nicely with the old sealant and the galvanized metal. I had to do numerous pours to fill in the dip 1/4” per pour. Noticed that the product shrinks when it dries. Since the product is not waterproof, I decided to finish with a waterproof coating. The cap will still hold a little water, but so do flat roofs.

I bought this waterproof tape,because it said it would work underwater. They patches I use from the pool store I usually have to replace every summer. I thought this would solve that problem. It did not minutes after my son applied them they started to curl back. This was all done underwater and he peeled it back underwater before application.

Purchased this seal tape over the Flex Seal brand, because I assumed it would be better. I am trying to stop a leak in an inflatable hot tub, the leak is from a a single cat claw hole on the top, not underneath the water line. The gorilla tape seems to be hard to stick to the surface, I even used rubbing alcohol to prep the area before applying the tape. Once the tape it only last 12 to 24 hours before peeling off and leaking. Waste of money.

Tried to fix a small hole in our pool liner. Couldn't get the tape to adhere. We followed every direction and couldn't get it to work. Very disappointed in the waste of money.
