- Well, that's as may be... I still don't see the nitrogen as essential
- to creating the head; from the message you quoted, assuming the poster
- is accurate, the nitrogen is used to reach the desired pressure in the
- chambers. MAYBE the can has nitrogen in it, but the smoothifier would
- work without it.
