Flex SealReviews of flexsealproducts.com

Used flex seal tape between two metal roof sections. It gapped and leaked throughout the job. I had to seal the gapped areas with roof cement.

Tried to use liquid flex seal above my windshield to stop leaking rubber seal, what a disaster, used painting tape above and below the area. Product is so thin and runny, it ran down over the 2 inch tape and about 10 inches onto my windshield, never again!! What a pain trying to get it off my windshield..

I bought a can of Flex Seal spray on. I needed it for a gutter running over my Lanai that was installed and only butted up against the 2 ends. Every time it rains it has a steady flow of water running onto my Lanai. I applies 3 different spray applications and only slowed it to a steady drip. I have no confidence in it ever working. I wouldn't buy any of their products, good advertising just on positive results.

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.
