I'm no painter. But, the one time I used them I could dip

I found the rollers from one store would not fit the handle
from the other store.

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?


If you can find an oil that comes in a spray can, sure you can substitute.
Perhaps you could put a couple of drops of sewing machine oil directly into
the can - it should migrate and spread to the top of the paint.

And you can perform the steps in any order you like, so long as the result
is the same.
