Needs foam spray gun to use, found good ones here for about $20 (look for the one with a shut off valve below the can mount- it works well for me- "SocsPark needn't clean"). I've since found that Great Stuff Pro at local stores also meets the standard for doors and windows.

This DAP product worked well. I was able to spray in cracks and crevices in a controlled manner without worrying about the foam expansion causing damage.
