Didn't work for my application

Didn't work for my application
I bought this to patch up a few holes in my insulation in my crawl space\attic. This is old school insulation that has a paper shielding. At first it seemed as if this tape was going to hold as can be seen in the pictures, but came up the next morning and it was all on the ground as can be seen in the other picture.It seemed really sticky, in fact it was so sticky, it stuck to my skin and my scissors causing them not to open without force and goo gone. Not sure if this is due to the cold (which means the tape cannot stand basic New England temperatures) or if it was the paper substance, but this tape just did not work and for $9 for only 5 feet, I was sadly disappointed.
Thank you for your feedback

When you cut the tape with scissors, there will be some tape residue left on the blades. When I was through cutting the tape I just used a little "goof off" and it cleaned easily. I don't know how it is to remove, I would only use this tape on something I didn't want to try to remove it from. If you hold the tape by your fingers for a little bit long, it really will stick but you can pull it loose. I would suggest not holding it long!

Useful stuff. I got it to repair garden hoses. Out of 5 patches, 3 held perfectly. The 2 biggest cracks I repaired, I apparently didn't get it pressed down smoothly enough. A wrinkled spot kind of acted like a tunnel for the water. The wrinkle made a tiny gap near the crack in the hose which filled with water and quickly shot water out the end of the patch. The flexibility of the hose made it a little hard to wrap the tape on exactly right & smoothly. I'll recover the leaking areas and try to correct the situation. The smaller patches are working perfectly.

I saw the commercials for this product showing a guy floating around in a boat with it, using this product to stick underwater, etc. I bought it to patch a tiny hold in my plastic hot tub figuring this was just the item I needed. I first attempted to put it on with water in the tub. The piece I put underneath the small hole with water in the tub did not stick. Okay, I thought, like the ads, I'll just put a piece on underwater over the crack. The second this stuff hits water, it doesn't stick at all. So that was worthless. Okay, I thought, I'll just drain the tub, put the tape on both sides of the crack while dry, let it cure and refill the tub. I was amazed at the lack of flexibility of this stuff, does not go around any sort of bend well at all. Regardless, put the pieces on the dry plastic, let it sit for 24 hrs, then refilled the tub. Within a couple of hours, the interior piece was flapping around in the water. The "stick" was completely gone in both hot and cold water. This stuff is worthless. I really hope no one is actually trying to fix a roof with it, water will go right through it. It does not stick when wet and barely sticks when dry. I'd like a refund, wish I could get a refund on my time spent wasted on this.

This worked great to secure the front bumper cover back on to my mail van. I had 'accidentally' struck far too many mail boxes over that last several weeks and my bumper cover kept coming off. This tape was the perfect size to stretch far enough to create a secure hold. It has also held up well for nearly 3 weeks despite weather, further 'accidental' mail box bumps, high speed escapes from karens, and the occasional alien abduction attempt.

I bought this 4" x 5' roll of Flex Tape to try on an old 27 year old wooden frame & fabric "kayak" (actually an old Folbot...you can look that up on line for what they are). Anyway due to age the original seams on the thick Mylar-type lower hull had separated a few years ago in 4 places, allowing water to come into the boat. I shelved the boat & purchased a nice new hard shell kayak. Recently I started seeing TV ads for this stuff and figured for $20.00 bucks I had nothing to lose so I ordered it on Amazon. My daughter & I went kayaking yesterday & I decided now was as good a time as any to try the Flex Tape so I cut (4) 6" sections to cover each of the seams. Upon peeling the backing off I was struck right away by the tapes flexibility. Very nice. And it clunk great to the boat seams. I made sure there were no air bubbles and we loaded our boats on the boat racks. Lots of chop, hard current, great boating !! Yes there was a LITTLE water in the bottom of my boat but I truly believe it's from 1: my initial entry into my boat & 2: waves crashing over & onto my boat (I did not use a cockpit "skirt". Anyway I think the tape did a great job!! Now I have my old boat as a backup or spare. This Flex Tape brought an old boat back from the dead.

 Me gustó que sólo limpié el área del tinaco y lo parché muy fácil, una vez aplicado es muy difícil de quitar así que se tiene que tener cuidado de no dejar arrugas en el parche. También reparé una cubeta.
