This is staying stocked in the farm permanently!

AMAZING product!! I used it to seal up a broken carpet steam cleaner water tank, and a livestock water trough that was cracked and leaking. The steam cleaner had a legit hole in it and it plugged it up and fixed it and the tough has been cracked for 3 years with nothing working until NOW! I'll be keeping it in stock on the farm and in my shop from now on!

Worked great for a quick fix

Had someone drop something and smash a U.S. quarter sized chunk off the interior corner of our shower pan, and used this to fix the hole. While somewhat difficult to smooth out for someone who is less than artistic, the product itself sealed up very well with no cracking or voids.
