Isn’t that what preppers slather on their guns before burying them in the woods ?
That might have been “cosmoline” in the old days. I remember that term only from the old Twilight Zone episode about the guys who put themselves to sleep in a cave for 100 years. I was surprised to see that it was a real thing, not a term and concept they made up just for that episode.
