Flex Tape Strong Rubberized Waterproof Tape, 4 inches x 5 feet, Gray

This stuff is an amazing and cheap way to fix a leak of any kind or size!!! I have not actually used this roll. But I have used Flex Tape in the past, and it is great! Easy to use, works really well to stop leaks. However, I'm not sure if it will work under pressure (i.e. pressurized tanks, etc.), never tried that. The only bad thing I can say about it is that it's awfully expensive, still cheaper than a plumber, though!

I purchased Flex seal white tape to repair my platform tent. A bear had ripped open one side. I sewed it up and put the Flex seal tape over the tear. The tent sits in the hot sun and the tape is still holding fine after several months. Great product.

I bought French doors for my living room maybe 8 years ago and the inside still looks beautiful but the wood frame on the outside was starting to rot at the bottom. I put flex tape over the wood frames and you can't even tell it's there unless you walk up to them and look for it. I'm hoping it at least buys me another year before buying new doors.

I had a shower pan that was cracked and caulked but leaked anyway. it was bad. to replace it would have cost hundreds of dollars and a lot of work and if i had to hire it out it would have been a thousand dollars or more. I took sheet metal and used flex paste adhesive/glue. i put a patch over the cracked area. after it dried i used seal tape, and then took the flex seal spray and went over everything. i used almond and it matched up OK. so far it has been a few months and it looks great and most of all i don't feel like I'm going to fall through and now it does not leak. I am very satisfied with flex seal products.

Very happy with the results. Sealed the greenhouse panels since they were blown out in a coastal storm. Since then have had high winds and they did not budge. Can't really cut a straight straight line with the 8" width roll as I made 2" long strips and it is rather gummy material. But no matter, I was looking for functionality rather than esthetics. Also, the large roll was much more economical for the project instead of purchasing 2" wide rolls

I really love that you can get this product in such a long wide piece. It worked really well when I put a small piece toward the bottom of my pool. I did find out not to use any glue with it as it doesn't stick as well when you do that. So, use it alone. It doesn't work as well above the water line, for some reason it seems to peel away over time. Might be the sun on it when it is on pool liner material? Not sure. I was disappointed when I could not find it in white like I had before but used the gray and that was okay. This last time there was a piece about 6" long where it did not have the backing to peel off. Therefore, that piece was no good. Other than that, I really like the flex seal, it works very well.

Used to patch a hole in pool liner. Within 24 hours the tape discolored. Within 72 hours the tape began peeling off the pool. Replaced the Flex Seal with proper patch... However it's good at repairing my bird feeders that have been attacked by squirrels.

I am trying to seal my moonroof from leaks with this tape. All the other similar tapes (like Gorilla tape) have worked, but the one I really thought would do the best job, even though it cost quite a bit more, isn't staying put like the commercials say it will. To say that I'm disappointed is an understatement.

Came unstuck after two days. I prepped the rubber upper of Muck boots by washing with soap and water, rinsing, and drying for 24-hours. After two outings with the tape repair, the tape began to unstick. After five outings, the tape was completely unstuck. Too bad!

I am so unhappy, I have used Flex Seal products throughout my home. Unfortunately the flex tape has let me down. I had a small abrasion on my pool liner and used flex tape before adding water to pool and after adding water the edges have started to peel up. I trusted flex tape to hold my 10 thousand gallons of water!
