Absolute garbage. Wouldn’t even stop a drip when the main water valve for the house was shut off

Product half cured when I opened one of two containers. I reached out to them over a dozen times via their website, email, and phone and they have not responded to my requests for info on shelf life and date codes...who know if this crap works in application because it's cured before I get the chance. Big dollars for something you can't use and has no support.

I've wasted nearly half of my roll of 4" clear because the backing is impossible to remove and the tape can't conform to my plumbing with it in place. A total WASTE of MONEY!

This product is a fraud doesn't work. Had a hole in my pool. From the outside tried to cover it while it was leaking. Stickiness went away as soon as water hit the tape. This product sucks.DO NOT FALL FOR IT.

After two years I think it's time to write a review, needed to seal up a couple of skylights in my shop because of leaking, summer of 2022 thought I would try flex seal liquid, gave it 3 coats, 3 months later... leaking, gave it 3 more coats, 4 months later leaking again! Last summer went up and 4 coats, well guess what... leaking again! It's probably been coated 12 times, I've got $400.00 invested in something that doesn't work and never will! Sure it works on the bottom of a boat as long as you put 5 coats on it and keep it in the water so the sun can't get to it! I would like to know how many times Phil built his boat before it actually floated! Too bad you lost a customer.

I paid over $30 for waterproof flex seal tape to patch the waterside bounce house and it would stick to everything but what I needed it to.

Bought Liquid Flex Seal and Flex Tape to have on hand for plumbing emergencies. Discovered a leak in a water line, no problem I have Flex Seal... Applied the Flex Seal tape to a clean and dry surface first, (start with the basic), didn't seal anything, just redirected the water to the end of the the tape. Removed tape, dried area again and applied Liquid Flex Seal, allowed to sit over night. Turned water back on and AGAIN it just redirected the water to where the seal ended. May as well have been craft glue or scotch tape - WORTHLESS. Now I have a can of liquid flex seal and a roll of flex tape but no longer trust it to have for emergency repairs. The commericals look great, too bad they are fake. Big waste of money, BIG waste.

Bought the basic Flex Seal flood protection kit and WHAT A WASTE OF TIME AND MONEY!!!! All the information and instructions were on frog only. Don't know who their marketing people are but they need a good kick in the ass!!! What bumb ass sells a product in western Canada without English instructions too.
