This stuff is so sticky it's dangerous. I am quite statistically challenged when it comes to pulling something off well so I've wasted a lot. Advice is to keep it in small pieces that are ready to go right where you want. Once you disconnect it, tear the non-sticky part off well right there if you've ever done something bad and unconsciously you know that it can be ugly you might just smash it right into the middle of your face! I do not even a little believe the commercial with the boat being held together by the stuff, I find putting it on wet surfaces to be more of the put a piece of paper on a wet surface experience still, I carry around for rolls cause it's good for making up whichever headlight or tail light you smash off, nice fits there. It'll fill up cracks (oh heck, maybe that's why she divorced me?"

Heavy duty and sticks good

It's not a fix all but roughly will handle 90% of what you can think of using it on. Big poly tanks even applied on the inside will not hold. Too much pressure. Otherwise small simple leaks, it works great

Meh. It's kind of hard to work with and didn't live up to expectations. The glue is very tacky, which I was initially pleased with, since I planned to use this to seal a crack in the pipe that runs to our garden spigot until my landlord could get a plumber out to fix this (the garden spigot isn't exactly a priority for him, so this wasn't going to be done soon). This stuff didn't work at all the first time, which I thought was just an application issue on my part, so I tried again... then again... Then I went to the hardware store like I should have the first time. For the first attempt, I cleaned the pipe thoroughly and it was completely dry. I cut off enough to wrap around the pipe, covering the small <1/4" split with the entire width of the tape and wrapped about 3" of tape around the pipe to securely hold it. I wrapped it tightly and smoothed out any air bubbles as I went to ensure the tape was making good contact on the pipe for it's full length. The moment the water turned on, it started spraying out of the ends where the tape met the starting point. I tried doing it a second time, this time drying the pipe again, new piece of tape about the same length, but this time I used a screw driver to use as a kind of bone tool to press the tape together at that first seam, thinking the tacky glue just needed to make contact and seal the little spot where the tape met itself. I also smoothed out air bubbles as I wrapped it. Still no luck. Third time, I took off the tape from before, cut only enough to warp around the pipe, so the ends didn't touch each other. Oddly enough, this worked... for a couple of hours of use. I had been turning the water valve on/off as I needed the hose, so the tape wasn't under constant pressure, thinking I could prolong it's use, but it lasted about 3 hours before a water bubble formed under the tape. Just like a balloon, once it started inflating, it continued until the bubble reached the edge of the tape and it was done for. If you need this for plumbing, I'd recommend against it. Just go to the hardware store and buy a pipe repair clamp and be done with it. The repair clamp was about $11 and has been holding like a CHAMP for 2 weeks now, this was $13 and seems like it doesn't meet even their own claims. Also note the description says the bond is permanent after 24 hours and cannot be removed... That's not true. It's as easy to remove after 2 days as it was after 2 hours. And if you have trouble getting the adhesive off of your scissors or knife, just use Goo Gone and it'll come right off. The adhesive oddly enough sticks to EVERYTHING you don't want it to stick to and scissors WILL get gunky after the first cut. Goo Gone will save your tools from this mistake of a purchase.

Works, but hard to pull off roll.

Not very much on roll for the price. Color was off for our item. Sent it back.

stopped a leak on Christmas Eve between hot water heater and the main house heat boiler. very cold out and little chance of a plumber.

I had a tiny leak of water coming in my floor on my 2014 expedition , I had found out the problem was the rubber seal cap from some random factory hole was leaking , I cleaned up the area and applied this tape with the plug still on,and I haven’t had any water come in from the floor going through rain puddles etc, I also used it cover tiny screw holes one might make installing things or removing installed objects and coming the hole. TAPE-wise 10/10

Both the side is quite stcky very hard to remove and fixing it on surface.

Excelente

Horrível não serve pra nada propaganda enganosa quando vc coloca solta tudo

Came very damaged, the sticky part melted all over the box. It's worst tape. Time and money waste.

i used it to stick plastic sheets at my roof of stairs for water leakage, its as of now good. not sure about longitivity..
