I have a metal garage 30x30x12 and I'm trying to insulate cheaply, so I bought 2 packs of suspended ceiling panels at the local Habitat of Humanity for $10. has never been used. I tried Loctite Super Max, whatever, and it sucked. There is no instant grip and they just didn't hold up well, most of them eventually falling off. I did some research and this stuff seems to get pretty good reviews. Well this stuff has a great instant grip. I hang it on the wall, place the tile in position and hold it to 30, and ding-ding-ding is the winner. Well, let's see how long this takes.
