Works if you follow directions

This Product totally works, just make sure you use a few coats and don't just load it on all at once or only use 1 coat. USE A FEW GOOD COATS and it will seal the leak. I purchased a pre-formed pond that had a crack & it looked like they tried to seal before but still had slight leakage. I removed all previous glues & just sprayed a few coats of this flex seal and the pond no longer leaks at all, completely sealed it up.

Roof Work

I bought a couple of cans of Flex Seal back when it was first advertised because nothing I had tried including asbestos impregnated roofing cement had been able to seal the joints in the ceiling panels of my four-season room. I sealed them with single applications of the Flex Seal. And, Bingo, my problem was solved. And they stayed solved until this year when, again, the panels leaked during one of our recent cloud bursts. When I found out that Walmart had the product and free shipping I immediately ordered three new cans. This time I double sealed the joints and the next time we had another torrential rain my little addition was dry as a bone. I'd recommend this product to anyone needing to waterproof a thin joint. Worked even better than taping the joints with strip caulk!

nice sealant

good for sealing cracks to keep out water..I use it around the foundation of the house.. I've had problems with water coming into the house when we have very heavy rain ... along with digging a ditch along the house, I use the flex seal outside and Flex Shot inside

I use it on my asphalt driveway and it works great

I use it on my asphalt driveway and it works great to cover and seal bad spots and tire tracks that have lifted up my coating
ez to use but can be messy (do not get it on your skin -- impossible to remove)

Works Great!

Works just as advertised. I used it to seal a large/long area in the bow of my 14' aluminum boat. It was easy to apply and doesn't take long to set up and cure. I'd recommend it!

Returned 3 of 4 cans.

I'd imagine Phil Swift was eaten by alligators after the screen air boat sank in the swamp with him. Not only does this stuff run everywhere, it peels off easily even after 48 hours dry time. It does not seal most leaks, melts if anything touches it with petroleum (Like a Gasoline Powered Air-boat), any minor fuel leaks on generators will melt it off. Would not seal a minor leak around underside of sink Garbage Disposal after 5 coats. Awful product, not only a waste of money, but a huge waste of time I can't get back. Overpriced and silicon rubber still works much better and actually seals leaks.

Great Stuff

Paid a roofing contractor to find and fix a leak around the fireplace chimney. He came back 4 times, rebuilt, reshingled, and still didn't fix the problem. I took this spray up on the roof, sprayed where the chimney meets the roof and haven't had a problem since. Could have saved myself hundreds of dollars if I had tried this first.

Flex Seal 7/11/13

I had a small leak between roof panels over enclosed lanai. I sprayed the seam in the hot sun yesterday and 6 hours later it rained 1.5 inches and I am happy to report, not a drop of rain came thru. The product did the job it claimed and was far less messy than using elastomeric spreads.. Michael, Spring Hill FL.

It works!

Was skeptical, but sealed major leaks in my skylight with one coat, if you are unsure, try it....
