So what do I do, just bag the item, start spraying it in he bottom, put it in the box while it's still expanding and keep spraying till the box is full?
That's pretty close to what the pre-made Insta-Pak bags are, they're just less messy. I think you'd probably want to bag the item *and* the box, or fill two bags (one on bottom, one on top, much like the Insta-Pak bags usually do). If you do two bags, just make sure your item doesn't sink all the way to the bottom of the bottom one or it won't be as protected. Note, of course, I don't know what the elasticity of Great Stuff is vs. Insta-Pak, which could make a difference for CRTs (mostly their internals). I DO know that expanding Great Stuff WILL force a doorway out of position (hard experience), so be careful; it does grow more than you might expect. - Dave
