This is great as long as you know its a one use product for whatever your project may be. You can't seal the container up adequately enough to prevent it from drying out. I would encourage you to purchase multiple small packages rather than one large one if you have multiple projects or just resign yourself to a lot of product loss. I personally used it to coat the ends of peg style towel holders so towels would stop slipping off the slick ends and into the floor. Worked, and I didn't have to remove old hardware and purchase new ones. That's a win.

Worked great to seal a beloved planter that was damaged by the weed eater. I don't have to worry about all of the dirt and water running out of it. Easy to apply and set up quickly.

Product worked very well. Good amount of workable time, spreads well with a small spackling knife. The only complaint is that the product arrived with the top 1/8" dried up and unusable, and since you don't get that much in the can, having to throw away about 2 spoons full is a real problem. They need to seal the can lid better.

Product was congealed in tube. Unusable. You can see from other reviews this is a constant problem that has not addressed. Very disappointing and unacceptable. Ended up with blisters on my hand trying to squeeze the caulk gun trigger to force the paste out of the tube. Finally gave up.

It does everything that they say. It is also very easy to work with.

Amazon's web page shows the "NEW! Stay Fresh Container", but they shipped the old obsolete plastic tub. As many of the other reviewers have correctly stated, the plastic tub cannot keep the product soft, pliable and usable. I called the FlexSeal factory, and they are fully aware of the problem. If you order from the FlexSeal website, the factory is shipping the Stay Fresh can as of 2024, March 12. This is a good product, but it's a complete waste of money to buy it in the obsolete plastic tub. That form of packaging is incapable of keeping the product in usable form. It hardens from the top down. I bought two from local stores, and learned that if you squeeze the tub at the top and it doesn't feel soft, the product has hardened and won't be usable. Typically it will be softer near the bottom, but all of the product above (the unsqueezable part) is so hard you can't get it onto the putty knife. Amazon needs to stop shipping the product in the obsolete plastic tub. Update: I called Amazon Customer Service and advised them that the plastic tub packaging is obsolete and no longer being shipped by the factory, and that they should return all product in the plastic tubs, and ship only the product (in the can) shown on the web page. I was advised that they would do so. That was on March 16, the same day I ordered the new (can) packaging directly from the factory. It arrives today (March 20). Shipping was free. Looking forward to seeing how it performs in patching a stucco parapet wall. Update: I received the can from the factory. The product was fresh and easy to apply. Because I was applying it on stucco, it took more to fill all the nooks and crannies than I expected, so I will need another can to finish the job. I ended up doing the whole job with a putty knife. I applied it in full sunlight on a warm breezy day, but it stayed flexible enough to work it into a smooth surface as I went. I doubt it will need a second coat. I don't know how long it will last, but I expect it will be pretty durable. There is no way any rain is going to get through the FlexPaste. I used a rubber spatula to scrape all the product from the sides and bottom of the can. Clean-up was easy; I just wiped the material off the tools with paper towels.

This is the only product that I could find that I could use in a outdoor fountain that has a thick EPDM GoodYear made liner that would stick, and that was safe, out of all the other products on the market. Thank you

Excellent for patching leaks in most stiff materials.

fixed the problem we had

Fast

Excelente producto, hace todo lo que promete. Solo lo puedes usar una vez, lo deje muy bien tapado como venía en el instructivo y se seco, pero cumple perfectamente su función.

I have used this in the paste tin format, and it is awesome. Having in a caulking gun format only increases the amount of awesomeness.
