I was wondering about using argon/co2 welding gas. Not sure if it'd be smart, but no O, or h2o.

I always (almost) flood the can with 100% argon through a crack just before closing the can. I don't know if it does anything but it makes me feel smart. Maybe someday I'll appear in one of those "old school guy taught me this" videos. It has to be better than my midwestern air.
