Storing finishes? Stopping stoff going off
What are people using to store finishes/varnishes/paints after opening the original container?
Is there some cunning airtight/air-free container out there? I have some pricey FW Floorseal oil which I know goes off, so I'd like to put it into some smaller containers that I can store longer term, and use one by one...

Google “stop loss bags”. Been using them for a few years now and they work well.
Edit, here they are. I got mine from Lee Valley but looks like they now stock them here: Stop Loss Bags - StopLossBags

Carbatec used to have bags to store product in once opened I have stored MinWax finish for probably two years so far still good to use.

Carbatec seem to be selling the add on bits like funnels, but not the bags themselves.
I've ordered direct from the US manufacturer. Dispatched within an hour or two of ordering.

I got 8 bags, a funnel (although I suspect any funnel will do), and a few spare lids for US$44 including delivery from the States. Which is about the same price as the bags alone + delivery from the locals.

Here's a tip I have heard about that I use with glue but have not tried it with finishes.
If you have a TIG welder that uses Argon gas you can easily displace the air in a can with a shot of Ar.
Ar is inert so the glue and paint should not react with it and it won't form a skin or degrade.

I have house made varnish (which is notoriously short lived - a couple of months of shelf life) in the stop loss bags, and it seems after about 6 months or so to be the same as new.
House made meaning made in my back yard by heating resins and oils until they bond (which is about 600 degrees F).

I think one answer might be to store varnish upside down. Then any skin that forms will be at the bottom.

Argon gas!
Big bottle at Bunnings for $40. Lasts forever...
Same as Bloxygen. It's apparently "ultra pure"... Whatever that means.
It's funny, I was reading about the compressed-air industry only last week. Oxygen, nitrogen, etc.... It's really quite interesting.
Edit: forgot to mention my mates at GasWeld. Awesome shop, well worth the time to look around: https://www.gasweld.com.au/shop-by-b...ze-pony-175676

Those bags might be perfect for my Cabots Danish oil, I lose a tin every couple years when it spontaneously decides to turn to gel!

Another trick I've heard but haven't tried yet is adding marbles to the container after each use. This brings the liquid level back up to the lid level thus expelling most of the air. Marbles don't cost much either. Ball bearings would also do the trick.
