Cylinder wall Lubrication for short term storage?

Cosmoline would be best. LPS-3 is very good and in a spray can. For few weeks those would be overkill and more painful to clean up. Motor oil, ATF, or a heavy gear oil would do fine. WD 40 would probably work but it evaporates after a few weeks. I've had poor long term performance from it so why bother? In the spring when the temp swings and cast iron sweats and rusts, in my unheated garage I like to cover my lathe and mill and put a 60-100 watt trouble light under the cover. The heat from the lamp drives off any moisture that wants to accumulate on the cast iron. Machines have no rust in fifteen years.
