I was just at my parents house tonight where my dad had a can of expanding foam insulating material laying around. Is this something that has been tried by anyone for scenery? Maybe just for filling in small holes or anything?? It seems like it could have some use. When it dries it's pretty stout and can be cut easily with a blade, and it sticks to almost anything it touches. Excuse my beginner question, but inquiring minds want to know.
