Don't forget, it also works for expensive polymerizing oils.
For latex, I buy $0.89 empty quart cans.

Since the problem child is latex, when sealing the can lay a layer of
plastic food wrap (aka Saran and a half-dozen other brands) across the
top surface of the paint. If it should someohw skin over, the skin will
come out with the wrap. You might also put another layer just over the
opening when sealing.
I tend to use mine up ... if I only have a half-gallon left over I'm
likely to go back over the room or whatever with an additional coat over
the parts (outside corners, near doors, etc) that are more likely to
take wear. You might also, as another poster mentioned, decant it into
smaller containers ... quart spaghettis juice jars should work just fine
and, with a small amount of foresight, be free. There -definitely- use
the cling-wrap stuff over the mouth and across the threads.
The key in any of these suggestions is to impose a barrier between the
paint and air or other contaminants.
The moisture that is causing the rust primarily comes from the paint
itself. Putting a barrier over it keeps it from losing the moisture --
and that keeps it from skinning over.
Just a guess.
I'm not not at the above address.
Finished a tank of ArgoShield for the MIG welder today and got to
thinking.... Recommended shield gas for general purpose MIG is 80% Argon,
15% CO2, and 5% O2. Just wondering if this would be a good substitute for
the commercial O2 displacement products such as Bloxogen. When I'm at
welding supply house tomoorow I'll talk about other mixes and prices.

I don't know if this applies but here goes anyways...At work I
sometimes store oxidizing chemicals with anti-oxidation balls. They
are just hard plastic spheres that float on the liquid. I think us
plastics sells them.
Keep the air off an oxidizer and it will not oxidize...I'd guess this
applies to paint as well.
I've got partial cans of exterior latex 20 yrs old (why?) that I put
Saran wrap over the top before I pounded the lid down and they were
still good when I opened them a few weeks ago. Plus it made them
easier to open. I did turn them upside down and shake them about once
every 5 years.

An el-Cheapo propane torch.
Been using one for years.
Whenever I buy a 4litre can of paint (water based), the first time I
open it I decant it into 1 litre plastic jars. This is of course if I'm
not going to use it all within a couple of weeks.
I find that when the next jar is opened the paint is like new.
