    • Pretty Hardcore!
Item Package Quantity: 1
Used this to plug a hole in a plastic dog grooming tub and it has withstood and held up for about 3 months with no signs of wearing. Was skeptical but it works! It did not however work on a plastic laundry basket that broke and had even done multiple applications. Worth the money for certain things depending on what you want to use it for. Easy to use but messy so make sure you do it outside or put a protective layer down and around what you are spraying. ... show more

    • Easy to apply
Item Package Quantity: 2
The home we purchased has skylight that began to leak. We used the Flex seal max to seal around the edges of the skylight. Using the spray type made applying the seal made it much easier to use than trying to apply with a paint brush. We live in FL and this is our hurricane season. It's been several weeks since applying the Flex seal max, and we have experienced no more leaks. This easy to use produce saved us a lot of money because we were able to apply it ourselves, rather than having to hire someone. ... show more

    • Not as good as it appeared on TV
Item Package Quantity: 1
I used this on some cracked pool equipment. The first time I didn’t fully follow the directions on wait time. The second time I allowed the product to cure fully. It lessened the crack but couldn’t repair it completely. It may work better on something not so pressurised.

    • Great sealant!
Item Package Quantity: 1
I had used this years ago when it just came out and you could only get black and it worked great although black doesn’t look great on all items! I purchased this to seal a leak in my roof, but you could use it for so many things. I’m planning to use it to spray some metal panels to prevent rust. I actually have several things I want to try it on so we will see how it works. I do know however that it worked great when I used it before and I definitely recommend it if you have a leak. ... show more
