Seals leaks very well

My Hot Tub cover was destroyer during a hail storm in Colorado. Pock marks all over and then we had rain forever so lots of water seeped in. Ordering is a 6 month wait...what to do? I have to make this cover last for as long as I could. I saw Flex Paste...... ordered . Took longer to get here than I thought but was worth the wait. It now looks like my hot tub has a bad case of pimples with Noxema on all the spots! LOL...but it keeps the water out and I can wait without worrying about the winter snow compromising the cover.

Same complaint as many others. I specific all ordered the can as advertised and it came in a tub. We had ordered a tub before and it looked like this when opened the first time.

Hi. I have purchsed this product several times, and am always hoping that the whole of the container can be used. I have purchased from home improvement stores as well as Amazon. I have purchased 3 sizes of containers, and all three had the same problem: At least 20 percent (or more) of the product has always been CURED in the container!!! My thought was that maybe I'll get more UNCURED product than CURED. I was wrong however I did get more product that was not CURED because the container was larger. I would have to say that atleast one-fifth of the Flex Seal Paste is wasted even BEFORE the container is opened. Buyer Be Aware.IF ANYONE HAS PURCHASED THIS PRODUCT, YOU KNOW EXACTLY WHAT I AM WRITING ABOUT.

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.

I have not applied the product yet to my wood building to fill screw holes due to weather. I am confident it will do the job. Update later.

Hard to find.

My husband used this as a sealant to waterproof basement walls in vulnerable areas. Then he rushed outside before the remainder could dry out and filled in two cracks in the driveway. Right after that he filled in a crack in the garage floor with what was left. He will cover the driveway with black sealer this summer and paint the garage floor, so those repairs should not show. Every summer he makes repairs to the driveway, and every year the cracks come back. He is counting on this product being the solution. If it fails, I will be back to update this review at that time.
