As Seen On TV Leak Seal

We had to pull our toilet and while attempting to put it back in place, it slipped out of DH's hands and fell to the floor. It appeared to be unharmed and we set it in place. We filled it with water and all was well. 2 hours later, I went into the room and found a small drop of water on the floor. Looked closely and there was a hairline fracture of the tank, about 3" long on BOTH sides of the tank. Dang, new toilet! Hey, we have that spray-on stuff. Let's give it a try. Emptied tank, dried it with towel, dried it with hair dryer. Applied a layer and let dry for 24 hrs. Another coat, let dry for 24 hrs. OK, let's see how it holds.

It has been 6 months and it is still holding despite us using the toilet 10-12 times each day. I am waiting for it to let go, but so far, it's working well.
