That works, but in general one should avoid painting from the can: Oxygen is
the enemy of paint!

Assuming latex paint, when ready to return the can of paint to storage,
follow these procedures to mitigate oxygen destruction:
1. Lay a piece of plastic over the upturned lid (cling-wrap, bit of plastic
bag, etc.).
2. Spray the plastic with PAM (original, not the garlic-flavored model)
3. Exhale into the can three times (to displace the oxygen with CO2)*
4. Hammer on lid with the plastic.
5. Invert can and store upside-down.

The PAM will migrate to the top of the paint and form a thin oil barrier
against any remaining oxygen in the can.

--------
* Or a squirt of nitrogen or argon gas (found in all well-equipped
workshops).

Sounds great. I don't use PAM or analogs.

Any other kind of fat/grease/whatever that I can apply to the plastic?

BTW: Should steps 2 and 3 PRECEDE Step 1?

TIA

I've read advice to lay the sheet of plastic wrap onto the surface of
the paint. I've never tried that, and just closing the lid very tightly
(a few smacks with a mallet) works fine for me. If I'm going to store
paint for quite a while, I place the can into a plastic bag so that it
is less apt to rust. I've had food cans rust through on the shelf and
don't want that to happen with paint.
