Sticks very well.
Works good, I use it to repair my hunting blinds. One is still good after 4 years of being patched.

works perfect
this stuff really works. I used it to seal a tear in a flexible, 150 gallon rain barrel, and it's actually holding up completely waterproof. it's holding even in freezing weather.

Great product but don’t believe what you see on tv
I purchased flex tape for a few different problems I had. The first was a leak in my water storage tank. The other was a crack in a pond. What I liked: ✅ Quality: very strong and sturdy material will definitely hold up over time. ✅ Seal: when used on a completely dry surface and smoothed out creates a water tight seal. Almost impossible to get off. What I didn’t like ❌ not as seen on tv: this product is shown to be able to apply on an active leak and still seal. You won’t get a perfect seal this way and have small leaks. Only apply to fully dry areas. Same goes for clean smooth surfaces. ❌ heat and weight weaken: if this is used where heat builds up and any sort of weight is applied at the same time it will loosen the adhesive. Overall I do like the product to patch things up but don’t use it like you see on tv. Fully clean and dry the area first. If applying to a surface with texture know that water can travel in the small crevices and still leak out.

Amazing stuff.
One of the best intentions ever.

Impossible to cleanly remove backing from tape!
I have used and worked with other similar tapes before, never have I used a tape where the backing was so awful to remove. First off, it was difficult to peel a corner to start to remove -‘that I was expecting as with most super sticky tapes like this, that is the case. However, once I was able to get a corner started, it didn’t matter how slow or fast I tried peeling the backing, it would inevitably rip/break and I would be stuck starting all over again. I could only peel about an inch and a half at a time before it would break - often unevenly, causing an even more difficult time to start a new peel. The even more frustrating part was if I already had a small part unpeeled, as I was struggling to get a new part peeling, the tape would inevitably stick to itself - rendering that part useless as it was almost impossible to unstick it from itself and still retain stickiness to stick to what you want. Most of this tape went into the trash. Luckily, Amazon let me return what was left. I had to find another solution.

STRONG TAPE
Very strong tape. Water resistant. Very sticky made it a little hard to cut. Was a little hard for me to separate the covering off the tape.

As seen in the infamous commercials
Just be careful when using them, they are 10 times stickier than your average tape.

Wasteful money on flextape.
Useless product. I bought it as my water tank 5000has a crack and was leaking. I applied the tape but of no use. It doesn't stick propely and my money wasted. Please don't get tempted to buy this tape. Only wastage of money and time.
