This is the technique I usually use. It's much cheaper and does the same thing. Don't bother holding it up. Just hammer a single finish nail in the middle of each bay and jam the piece of foam onto it. And you might as well spring for a 200' kit for that. It'll work a lot better than 70 or 80 cans of great stuff. You could do that if all you are after is air sealing but if you want any kind of insulation you'll need so many cans that it would be ridiculous.
