WD-40? Cures what ails you.
It’s some kind of Remington product.
Rem Oil
Wd-40 dries out and leaves no protection. It’s primary purpose is water displacement.
WD-40 actually does a good job of REMOVING lubricants. I even use it to get petroleum stains out of clothes.
If you want to destroy an air-tool, spray WD-40 in it. I learned that after loaning a few out.
