Question regarding the use of Argon gas to prevent finishes from harding in orginal can.
Can a mixtue of 75% argon and 25% C02 gas be used to keep the finish fresh?

Dunno. There’s stuff in a spray can called Bloxygen. Old wisdom is if you
exhale into the can it forces the air out and helps keep the finish. I do
it with varnishes and it seems to work though I haven’t done any real
testing. Oxygen displacement may only work to preserve finishes in
the can when the finish cures by oxidation, like spar varnish or poly.

I’m with Loren. You don’t know how many funny looks I’ve gotten when I wheeze into a can of finish. Sure is less expensive.

I have used my mig gas to do this and it seems to work and is cheaper than buying Bloxygen.

Hey! I missed one. Try drinkin’ a big dose of a single malt scotch. Then exhale in the can. Can’t hurt the finish, and it will sure help ya.
BOOOOOO on me!

I just fart in mine. Makes it last a long time and I don’t have problems with others ‘borrowing’ my finishes.
