GorillaWaterproof Patch & Seal Tape, Black Tape, 4" x 10' (Pack of 2) - 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.

The Gorilla Waterproof Patch & Seal Tape is very sticky and holds on extremely well, even in outdoor conditions. Once it’s in place, it stays put, making it perfect for tough repairs.I used it to patch up the under skirting on my camper, and it worked great—created a solid, waterproof seal that looks like it’ll last a long time.Bottom line: Super sticky, durable, and reliable—excellent for camper repairs or any job where you need a tough, waterproof seal.

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.

Wow! REALLY WORKS!So happy with this product. The tape is Thick and it Sticks even under water.So far, for over a year now, it is still holding my pool liner together.
