I heard about the propane here & tried it. It works great with
Rustoleum & not at all with Benjamin Moore. The B-M will be skinned
over in 3 days, even with the propane. I also tried CO2, with similar
results. Fortunately I don't use much oil/alkyd paints nowadays.

What about argon from a tig rig?

How do you accomplish that? Do you just flood the inside of the can
and then slam the lid shut? Although that seems to be the most obvious
way, with this group I would expect to read about welding a schrader
valve onto the lid (with tig, natch) and pulling a vacuum before
introducing the argon. It *would* make it tough to stack the cans,
though.
