GorillaWaterproof Patch & Seal Tape, Black Tape, 4" x 10' (Pack of 1) - Permanent Weather Resistant Seal for Leaks and Repairs

I used this to patch a strip of the fiberglass on my motorhome that had become separated and delaminated from previous water damage. It holds amazingly and will keep things in place and dry until I can fix the issue with epoxy. It's very sticky and thick.

Purchased this to seal the roof rack mounting holes on my 3rd gen Tacoma. So far, it has worked perfectly—no signs of interior leaks even after heavy rain. It adheres strongly and has held up well. I would recommend it to anyone looking to complete a similar project or needing a reliable waterproof seal.

Used for patching an above ground pool. Definitely could use instructions on use for that; apply on the inside. It worked well enough on the outside but one failed. Once I realized I needed to place it on the inside it worked great.Super sticky and thick which can be challenging to cut. Precut 3 or 4 inches would be easier to use.

Super sticky. Great for sealing. This not duct tape so be sure you put it on right the first time.

I bought this because we have a garden room with a metal roof. It was leaking at the seams. Rather than have the expense of getting a roofer out here, I decided to try this as a solution. I had to buy four rolls of tape. Started with just two to make sure it worked and after the first rain storm when no rain came through where I had taped it, I bought two more rolls and finished the job. It's held up well these past few years and I have bought some to give to my brother who is fixing his roof as well.

My snow plow truck is 27 years old and looks every bit of it—rust everywhere, including the windshield frame. It leaked so badly into the cab that I started keeping body wash and shampoo in the cup holders so I could clean up as I ran errands. Apologies to the family in the Buick who had to endure the terrible pitch of my singing at the stoplight, but hey, I’ve always been one to sing in the shower.I didn’t just slap this Gorilla Waterproof Tape on—I took my time, carefully applying it. At first, it looked really, really good. I’m including a picture of what it looks like now—spoiler: it’s seen better days, but it’s still holding strong.After surviving the worst winter in over 100 years—200+ inches of snow and a brutal ice storm—there are still no leaks. The tape did its job, and I’m impressed.If you need a tough, reliable fix that’s not in any manual, this Gorilla tape earns every one of these five stars.

What's going on with the quality of the products over the years. Bought couple years ago, worked great in the water and whenever I need. Bought again this year and nothing like the one before. Does not stick in the water or seal, still leaking. I was disappointed.

We used this on one of our (several) inflatable bouncy houses. It works great, is VERY sticky and has held up so far, been about 2 weeks. It is a thick tape, so it does not sit flush with the fabric. We also tried to use this on our water slide outside that has several holes, but it immediately got ripped off when the water came in contact with it. I realize this isnt the best use for it, but just sharing in case someone else was looking for a hole repair tape for a water slide.
