Had an outside door replaced and needed to seal the gap. Our 115 year old home is not quite square and exact. This stuff sealed it right up!

Busted container! But made right!!

Top busted out, product dried and clogged...although the product was damaged, it was made right, and I am very happy . Thank you amazon! !

Great stuff

Great product. Fixed a leak on my truck’s rear window that had been replaced. Window guy had already been back once after ongoing leaking. 2nd time he didn’t show so I bought this stuff after seeing the goofy add on tv. Easy to use I then tried to use it to fix some old, comfortable work boots that were originally waterproof, by “caulking” the junction where the leather meets the sole. NOT a good solution for that, but I was curious if it would stick.

Great

Excellent. Enter than using a chalking gun n comes with a clear cap that stops the flex seal from drying out

does what it says

really kept the leaks out of the house

Great stuff.

I used this when I had a leak on a roof and this stopped the leak. I plan on keeping this around for future issues.

exactly what was needed.

My fiance used this to seal around his window on his old car and it worked great. He only used it on a small section though.
