I think the confusion stems from the fact that I really don't know what I'm talking about. It's actually called Press'n Seal and it's by Glad and is available in every super market. I've been calling it the wrong stuff for weeks. When I got the box to take this picture I found my error. You can also use it as a mask for painting models, but it's sometimes hard to remove. It's good for canopies since you can see through it to cut around the frames.
