Flex SealFlex Paste 3lb (Black) Tub with Allway Tools Putty Knives 3-Pack (1.5/2/3-Inch) (2 Items)

I sealed up a 2016 Freightliner Cascadia. The truck was leaking between cab and roof. It's a on going problem with this cheaply built truck. Sealed it up good. Taped the seam up put sealer in seam pulled tape after set for 1hour.

I have used a lot of sealers, caulking and adhesives, but nothing that works as well as this stuff. It turns into a durable rubber when dried, that sticks to whatever it’s applied to. Great quality sealer.

Stuff works great but price is high. I don't mind but customers think it is crazy. They talk about home Depot stuff. Obviously not as good but much cheaper. Lots of people only see price.

i have a wall that had 2" cracks in some places & within 15 minutes i had the cracks filled & smooth. by the next day the area was firm & by the second day it was hard. it has been a couple of weeks now & you would never know where the cracks were.

Unfortunately, I love the product itself. A little messy, but it works as advertised. The reason for the low rating, the product had solidified inside the bucket upon arrival. I had never used this product before and wasn't sure if they purposely maintained a "film" over the top to avoid the entire product from being exposed to air. After applying half of the 3lb bucket, I realized the "film" actually was unusable product. I probably was able to use only 75% of the product.

It does what it says. Highly recommend. Bought a 10-foot pool for my grandkid there were leaks everywhere. Flex Seal fixed most of the leaks I was able to get to. The rest next year.

The two thirds still paste seemed fine, but it has not rained yet and I am not certain it will prevent water leaks into my garage. The one third that was dried out was completely useless, impossible to use, and a waste of money.

Top was completely dry had to pull that off but under it was good. Applied great and is holding up still
