Hello readers of the Flex Seal survey. For me the product failed without question. I used it on my Patagonia backpack in hopes of being the backpack back to being waterproof again. It looked great on day 2, but on day 3 and me continuing to use the bag in my daily routine the Flex Seal starting peeling off the bag in large black piece. Not what I was hoping for in the end. I would like to try the product on another project. Giving it another chance, still wanting to see this waterproof rubber like substance do what the info commercial claim.

Upset!
I bought this to stop air from coming in from around the window and it did not work. I apply three applications but still didn't work. It might have worked if I applied it in the Fall or Summer but probably too late in the Winter.

    Stopped basement wall leak
    I have a concrete basement wall with a crack that would leak every heavy rain. I applied 3 coats of this (2 days apart). A couple spots still leaked a bit so I applied 3 more coats. Few days later got 5 inches of rain and got zero leakage! Great stuff.

      EZ to use and Handy
      Flex Seal is easy to use and comes in handy when needing quick repairs for a leak. Just open and spray. I was able to seal my roof shingles after a recent hurricane. It did the job until I can have repairs made.

      Doesn’t adhere at all on vinyl
      I used this product to seal a few holes in my pool liner and it didn’t adhere at all, I wait 48 hours, I put water and immediately it began leaking so my wife got inside the pool and the product adhere all right, to her foot.

        Stained my Foundation
        Purchased to seal my foundation because we flood occasionally. It can best be compared to rubber glue in a can. It sprays everywhere. If you turn the can upside down to spray hard-to-reach areas, it stops spraying. I sprayed the foundation and siding, waited 1 week for it to dry. It gave my previously white foundation, a spotted wet look. Siding is also stained with this spray goo. I don't yet know if it worked.

          Not Bad but Could be Better
          I bought some Flex Seal as part of some random supplies to go on a boating trip because I'm the type of guy that overpacks tools and accessories hoping that I will never need them, but knows that it's possible that I might. Well I was out on the lake with my deck boat and ended up getting a bad small that seemed like it was coming from my outdrive. I unscrewed the dip stick to check the oil and realized that the dip stick threads were completely stripped (the top of the outdrive is above the water line when not in motion). There didn't turn out to be any issue with the oil, but now I was stuck with a dick stick that was no longer water-tight that has to be in the water. I wasn't in a place that had a good cell signal and had to get back to the marina, so I used some Flex Seal around the head and then used Flex Tape over the whole dip stick and port and ran my way back in. The Flex Seal did a decent job of covering the area around the dipstick to seal up any possible places where water could penetrate and get into my outdrive's oil. But it was the Flex Tape that really did all of the work. I did use some Flex Seal around the edges of the tape where the tape didn't lay perfectly flat, just to make sure it was completely sealed up. This product is very flexible and pretty easy to apply. The product kind of gets all over the place, and it is suggested that you apply several layers to get the best possible seal. The product doesn't work great under pressure, but if you're just sealing up a small gravity leak then you should be fine. If you need to seal something under pressure then you should really go with the Flex Tape. To get the product off of an accessible area, I used a drill with a drill eraser and it came right up. Flex Seal doesn't work well on areas where the the seal is over a broken area, the broken or cracked pieces are still able to flex under the pressure.

          Received OLD Products
          I received old product that seemed to be laying around in a warehouse somewhere. I ordered several colors and all of the colors were old. Some had damaged lids. I was very unhappy with my purchase. The colors did not seem vibrant when I attempted to use them. I shook the cans for about 15 minutes at some point and still had the same result. Very disappointed.
