well most of it anyhow. what a pain. I live with a friend who bought a mobile home. Its on the older side of things so it still has the aluminum roof. it leaks in one of the rooms so we figured we had better seal it up again. i hope i never have to walk on one of those roofs again. never have i felt something flex under me so much. i've walked roofs a lot before being a window cleaner for two years but this was scary. i was using a half sheet of plywood to stand on... all i have to say is i hope that crap works!!!
