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

So far so good! Waterproof tape is keeping two pin hole leaks from leaking. Here are the steps my wife and I took to help ensure tape held on the dry and wet side of the pool wall.Step 1: I applied pressure over hole from the inside of pool filled with water with finger to stop hole from leaking.Step 2: Then my wife placed tape over hole on the outside of pool.Step 2: So not to lose the location of the hole I kept my finger over the hole on the water side while my wife gave me another piece of tape to place over the hole that was under water. Yes, we put the tape over the hole that was in the water and it is holding up so far.

As far as I know it is and has been holding a 500gal. Holding tank together at the bottom in AZ. cause I accidentally left my cats paw nail puller underneath it and then filled with water!! Well worth it even for temporarily thank you gorilla glue water tape!

I catch rain in a hdpe barrel and some how got a hole in it the size of a pencil. It sealed and doesn't leak. Works very well. Seems very strong and grips very well.

I bought this for a leaky pipe in my backyard. It was easy to apply and seems to work. Only gave it four stars because it took a couple of tries to get it right. I bought the black one not clear in case that makes a difference. It is very sticky and a perfect width.

did the trick

Got it for college son's air bed. I knew more complicated patch options would be difficult. It worked great, so far.

I am taking a chance on this. Its not like I am going up on the roof after every rain and see how well its doing. Roof shingles would normally seem to be a craft that has been pretty well figured out by now, but you can find a thousand different opinions on what is required to make a leakproof connection to your roof when required. Our top of the line shingle manufacture won't honor their warranty at all if anything is done to their after installed roof system. They don't even want anybody up there to inspect it. I will need to make some contact points in the spring and might re-review this after I check out the performance of this product.

I repaired a 1-1/4" tear in a treadmill belt using glue and tape. The tear was at the seam, on the edge of the belt on a ProForm treadmill. I used "Super Glue for Rubber Repair" and "Gorilla Waterproof Patch & Seal Tape 4-inch". After two weeks of treadmill use, it has held. How: Carefully glue the tear on the top of the belt (the side where you foot strikes). Ensure you have cardboard below the tear so the glue does not leak thru the crack onto the board below. After the glue dries, cut the tape to fit over the tear. You'll need two pieces for top and bottom. Remove the protective tape and place sticky side over tear. Repeat for other side. I then stepped on the tape to make it sure it was securely in place. I also placed a small amount of silicone lube on the tape seam, bottom side to keep the tape from sticking on the rollers & board as the machine was running. $22 in glue\tape was much better than spending $120 for a new belt. UPDATE: The tread will heat up when the treadmill is in use causing the adhesive to ooze out of the side of the tape. This happened on the leading edge of the tape causing it to catch on the tread cover and lifting up the tape. I have replaced the tape and when the adhesive started to appear from the edge, I remove it by rubbing it off. Not sure this will keep the tape from coming up but will update this review if I have problems.
