Flex Seal White Flex Paste, 3lb - Crack Repair Bundle with Putty Knife Set + Daley Mint Cleaning Towel | Quickly Fills Gaps, Holes, Leaks

Seems to work very well, as described. But, you're lucky if you get half of the product volume from the small can and 2/3 from the larger one. The rest is a dried layer at the top. Don't be upset. Just expect it. It is what it is: A fast drying one-part product. I guess it is the nature of the product.

I ordered this product twice and both times the product was hard and dry inside the tub when I opened it. I was only able to use about half the content but the part that I did use was extremely difficult to work with because it was close to being hardened. The first time this happened I gave it a pass. Thought it was just old but then ordered again and it was the same. VERY DISAPPOINTED and I haven’t even finished the job because I can yield enough from what i bought. Need more but reluctant to buy.

Junk its like a hard chunk! Waste of money

There was a thick layer of the material on the surface and only a small circle in the middle was soft enough to be applicable with the spatula! Is this normal? Not satisfactory for me! Very disappointed!

used before, patching cracks and holes upright

Received product and went to use it. Product was sealed with foil covering and had silica packet inside. Still, however, the product was dried around the edge of the container about an inch forming a ring. Rest of product is usable and works decently for what I need done. Kinda hard to spread if you got uneven surfaces cause it likes to fill those gaps. Adheres nicely to the surface I'm putting it on (wood/metal). Just be aware purchasing here that product may come dried out due to whatever storage conditions/shelf time has elasped before you purchase it.

It did its job well (air conditioning duct repair) but it hardened completely, even with container closed, it did not store well at all. It's a good product if one uses it completely and does not save the remaining material.

I originally used flex seal tape to patch a hole in my vinal pool near the drain plug, a precarious spot. I applied to too under water and it worked all season long! This year, in preparation of the upcoming pool season, while the pool was empty, I took the old tape off, admittedly a potential mistake, and replaced it with a new piece. After filling the pool it leaked, and the hole seemed bigger. Impressed with the flex seal family of products, I searched for another solution and found the paste. It didn't say it worked on vinyl - so I took a risk. I applied it to the hole after taking the "new" piece of tape off, under water! It totally worked and you could see the pasted filling the hole from the outside of the pool. It was a little dry on top, who knows how long it was on the shelf at Lowes. It originally went on easy, but found it a little difficult to spread once originally applied. There's a little bit of a learning curve to spread it evenly, but it may have been the fact that I was under water doing it. However, long story short, the pool is no longer leaking, and now only time will tell if it works as good as the tape did all season. I recommend both products for underwater repair on vinyl.
