So long as we have one another to rely on we'll muddle through no matter what we have to do to make photographs.
Further update: I rebottled the concentrates in glass and under butane and something is crystallising out of the developers - I can see a "shell" of clear crystalline matter forming on the bottom of the glass bottles. I made up a batch recently and while it works and the contrast is right, there is a distinct blue tint so I suspect a correction to CD pH is required.
I'm basically posting EVERYWHERE ... anyone with a Fuji E6 kit in the states?
Yep, the postie.
Use a squirt of butane or gas duster gas on the concerntrates before tightly replacing the caps, that will sort them out or rebottle them to the brim. The tetenal E6 ones seal well, which is what i use so butane or gas duster works well. Tetenal working solutions i have kept at just below room temperature in a cupboard under the kitchen sink, in airtight collapsable bottles tightly capped. Longest i have kept a good working solution is 3 months, i usually use them to capacity well before then.
BBQ- or cigarette-lighter refills from the hardware store. Usually comes in ~300g cans.
Squirt a good blast of butane in the bottle to displace most of the air and keep squirting the liquid butane against the inside of the neck of the bottle for a second so that an icy crust forms, then you put the lid on. As the crust evaporates, the pressure in the bottle will go way up so you then release about half the pressure with the lid, which will get rid of most of the rest of the air. Don't let it get quite back down to atmospheric pressure - you want any osmosis/leakage to be outwards.
