BLOxygen is just argon in a small can, if I understand correctly.
The stoploss guys should make a gasketed spout so that a small amount of finish could be dispensed and no additional air would get in even while dispensing. a cap to close it for storage would be good, but if there were a second cap with a gasket, the finish would basically never see air of any kind while in its container. 🤔
The second best option, as far as I can tell, would be a gasketed condiment bottle stored on the cap with argon/BLOxygen in the empty space. Similar idea to the two screws, but stored and dispensed in a way that would minimize air entry.
