Jess and Cory, thank you for the birthday wishes, Cory belated happy birthday to you also!
Great Stuff is kind of a family joke for me. My dad was using it one day, years ago, when my daughter and her mom walked in for a vist and found him, the family room, and the couch covered, and my mother having a conniption! Since then, there is at least on can of the stuff at Christmas!
It does adhere pretty well, I know one person who uses it to make molded backgrounds for tanks, which he then paints and seals.
