This stuff is amazing!

I used this to repair a flat roof leak at the canally, the leak was pretty bad and did damage to the wall and ceiling, I saw this on line when I was shopping for some kind of solution to the leak and it worked great, I applied two coats and used the entire can, we just had a huge rainstorm that came through and NO LEAKS! This stuff is amazing! It has been raining off and on for the last two weeks and no leaks.
