After using it a couple of times, how long can I keep a can of good
quality eggshell paint before the paint is not usable?

Depends on the paint and storage temperatures. I replace the air in the top
of the tin with propane from my gas torch, this makes my paints stay good
(with no skin forming on oil paints) for much longer.

Interesting idea Mike! I'll have to try that.
I invert my part-used paint tins for storage. Any skin that forms is
left in place. Stirring does have to be done with care though!

IME its hard to predict. Some paints are useless after months, some
are still usable after a decade. Tipping the tin upside down then
storing it the right way up improves the sealing.

I suppose in principle it might help to turn them the other way up
every few months in storage, never tried it.
