Perfect product to save the day!

I like having the option to paint this product on! It gives you way more control over where it is applied, compared to the spray! I have used this for several different applications.I have painted window sills, that my gutters are back dripping onto, it repels the water & keep the wood from rotting. I have sealed gutter seams that were leaking. I painted the inside of a metal trash can that I am using as a Faraday cage to protect my electronics. I figured a layer of rubber would definitely help break the conductivity & keep things safer inside.It does have a VERY strong odor, it took me several days to air out the can I am using for my electronics. Once it is completely dry, it does start to fade, but not completely.Having this around to use & being able to apply as much, or little as I want, is why I got this in a gallon size. You just never know when you are going to need it & when you suddenly do need it, it is nice to have more than a cans worth, which can run out pretty fast when there is actually a situation that needs tending to in a hurry! The fact that it is clear is also a bonus, it works with what ever color your using it on.

Clear is Better

This stuff really works. For my rain-soaked RV along Oregon coast this product is absolutely necessary!The clear liquid (there's also white) for me is best. The white is quite bight and you can see the white patches everywhere. The clear liquid is just that- paints on clear, no white patches. It's up to you..

Great Product!

I used Flex Seal after contacting the company on my swim spa cover after a lot of hail damage. Not only did it work well it was extremely less expensive than a new cover! 1 gallon only covered half of the cover so I ordered a second gallon. I highly recommend Flex Seal!

Great stuff

The best stuff to seal and waterproof, especially around areas where water may leak. I had an older washing machine. It started leaking, but I did not know because it went to the back side and ended up damaging my ceiling below. So now I sealed the whole area so if there is ever a leak again, it has only one direction to go and that’s out the front where I will see the water.

Fles Seal Sucks!

This product sucks! had a thin crack in a tub that I wasn't ready to replace, so I thought I would do a fix that would give me a few months to fix it properly-replace it. I hired a contractor to apply 3 coats waiting 48 hours in between each coat. I thought we were good to go. The product started peeling off with the first shower. Don't waste your money, don't buy this product.

Work fast!

It works amazingly well, however, bought a gallon instead of quarts as needed more than two quarts. Next time will buy by the quart, it sets up fast. Had a skim in can after just a few minutes of use in shade and 70 degree weather. Put a piece of saran wrap over top open enough to expose room for brush or paint paddle which I found worked best for where I was placing. Skims back over after each use. It gets on everything seems like also, drips from the can on transfer will coat whatever you are working on.
