    • Simple, small cans of FlexSeal
These work great. I prefer the small cans as I never need to use much at a time, and sometimes if you use a large can and then set it aside for months/years the product will have solidifed in the sprayhead and the rest of it becomes useless. With these small cans you're unlikely to waste as much, but you may need multiple cans for a large job. In my case these were most recently used for a drain pipe inside my wall that had shifted and cracked at the wye-joint. Obviously this is something that needed a proper repair, but several coats of FlexSeal spray over a couple days took care of the problem. I will still get it repaired, but there's no more leak while I wait for the plumber to arrive. ... show more

    • It seals real well!
I have used this product and it always does a good job. I use it to put a rubbeer coating on my drum sticks for better gripping and it works fine.

    • Objects on screen can be smaller than they appear!
Very pleased with the product, just learned the hard way that I need to read the measurements to know how big the cans are! ;)

    • Worst product I've ordered from Amazon
First off, even though it said "mini" it was VERY small. There was not enough in ALL 3 CONTAINERS to even equal one "full size" can. When I tried to return for larger product, RETURN WAS NOT ALLOWED BECAUSE IT IS LIQUID/FLAMMABLE. Amazes me that THEY can ship "liquid/flammable" products TO me, but won't allow me to return an inferior product. I am very disappointed in this product and in their return policy! Since I couldn't return, I went ahead and used and, as expected, all 3 cans didn't even cover 1/3rd of one full size can. ... show more

    • Works great
Sprayed it on the inside of my 20+ year old Alice backpack top. It stoped all the water leaks. What a grate way to restore the leak resistance to my loved pack.

    • Had to use several coats and it was a small crack and it's still barely leaking
We used this for a water feature that had a small crack. We used several coats and it's still leaking. It's a tiny leak though. We used is on ceramic maybe it works better on other materials

    • Do not waste your time and money on these broken, tiny cans.
Don't waste your money! Tiny cans that arrived with broken caps and nozzles. The tiny size of cans is my fault for not ready the information better. What arrived was useless and made a mess!! That is not my fault! What a waste of money and time! Do yourself a favor and go to a hardware store where you can buy this product in person. ... show more

These are 3 small spray cans. That’s what I wanted . No problems with clogged spray. Just use and dispose.
