How dense is the substitute gas, compared to JP I mean?
Serial it should work as long as the compressed gas has similar physical properies to air.
I dunno bout argon but nitrogen should be a no-brainer (webby) cause air is mostly N2, no?
Argon is denser, and is sposed to be a nert so no chemical reactions would be made during spraying, doan think that's an issue. Argon is soluable in water but not that much more than N2.
But it's 'spensive compared to air!
Seems like it'd be cheaper to affurd a good compressor after running through a couple bottles or argon.
