Have read multiple threads about storing partially used cans of finish with bloxygen, nitrogen, CO2, marbles, vacuum extraction device etc. Every once in a while someone mentions using propane as a heavier than air gas substitute but there has been surprisingly little follow up in the way of response. One person says he’s used it for years, one was afraid of using a flammable gas, one said it gave on off smell to latex paint..as far as I can tell (and I did search the topics and posts pretty thoroughly I think), not much else..
Anyone else with other thoughts or experiences?
Thanks
Jeff
