Is there any reason that using CO2 is superior to using compressed Nitrogen
cylinders?

Nitrogen is an inert substance and is a major component of air (about 80%).

"The only problem I see with c02 are that it creates an acid when exposed
to water (soda water), and of course, its a green house gas, although
the amount used is probably insignificant relative to a car.

Good point, although if the film is dry, it shouldn't be a problem. As to
the greenhouse gas business, I use a 20 pound cylinder, the same as used in
resturants for soda machines. I use one a year, maybe two if I'm doing a
lot, so I probably don't do as much damage as the average McDonalds.

I am going to try it on something not important, though.
