Review: So easy to use! - This was so easy to use and worked really well! I am not even close to being a plumber, but this sealed my leak up. Used on old copper pipe in my basement. Drying/curing time was fast and the leak stopped almost immediately. There was enough to seal around my pipe with some left over. Not sure it would be enough to do 2 full fixes but a good amount.
Review: It worked really nice. - They have worked really nice, I am surprised! I used lots of other technics I was about to give up but this worked. It was easy to apply totally surprised me to hold until that pressure.
