  1. J. Holt

    I used this product as a temporary fix on a door step, so it needed to adhere to carpet, wood, and metal. It did just that. Very easy to use, although one must be careful and precise as it is very adhesive and will stick to itself if not placed slowly and carfeully. I needed more in the length but for smaller patches it is great. I will reorder soon as this tape seems so far to work as stated. I also will be ordering other Flex seal products for other projects. Very pleased!

    FABULOUS!!! I have been trying to figure out some kind of covering I could use on the “portals” that came with the used vinyl greenhouse someone gave me a few years ago. All the other means have lasted at most a month–rain (and snow) eventually dissolve the glues, tapes, etc. that I’ve used to hold up vinyl coverings. A month ago, I made flaps that I sealed at the top with Flex Tape, then applied heavy duty Velcro tabs to the flaps and the greenhouse itself to keep the flaps down when it’s cold and rolled up when it’s hot. Except for two Velcro patches above the flaps, which I may have to replace from time to time–they’re only “weather resistant”–all the patches are under the flaps and protected from the weather. And where I taped that Flex Tape–GREAT seal and no sign of any deterioration. I’m going to use Flex Tape on all the holes that have resulted from branches flying through the air and barn cats that won’t leave well enough alone. If the tape didn’t get a bit yellow, it would be perfect. But after so many failed attempts at other solutions, I’m thrilled with “fabulous.”

    Man, this stuff sticks!!! But I learned the hard way, don’t use scissors to cut the tape! It sticks to the scissors and can ruin them. I ruined a really good pair of kitchen shears trying to cut it. A good sharp knife works best for me.

    Definitely thicker than I was anticipating. I was hoping it would be the thickness of packing tape but instead it’s more like a command strip or even thicker. Used to seal a crack in the bottom of a cracked vase, it did the trick but definitely thicker than I had hoped (that’s what she said).

  5. Double A-Rod

    I think that this product is over-rated, and the commercial (which I knew already) is a lie! It may help in “some” instances, but “Hear ye’ me,” it is not as sturdy and strong as advertised!!!!! I have a pinhole on the surface of my inflatable hot-tub, and patched it so that I could refill with water. On the next morning, it was semi-inflated! Then, I order the Flex Glue to fill another spot and THEN cover the glue with the Flex Tape to further ensure bonding, but “not!” I will use the product, as I am sure that it may be good for something that doesn’t require plugging, but it is NOT as advertised!

    It was a bit “sticky” trying to cut the product to the size I needed. It was used to secure a “almost” sealed joint on my pool’s solar system.

  7. Been There

    Just used and must say does bond like glue! And if it gains strength over time, like cement! Perfect! Only drawback is one roll is not enough. Nearly the entire roll to tape on ac hose to unit(always falls out)… pretty sure this tape has fixed that issue! Want more, much, much more! Oh, also have a super sharp pair of scissors cause is a little tough to cut but makes sense because of its strength. Absolutely buy!!!
