OEH, when I was servicing time movements on bank vault doors,
I used Moebius grease on the pivot points. It was swiss made for
clocks and movements of all kinds. It is the grease from the Jaw
Bone of the porpose. I think it was world banned. Still have a small
jar and have used it in the action of my rifles. On the locking devices
of the vault doors, I used Super Tect white grease. Highly resistant to
water or evaporation and will not harden or break down under pressure.
Lubriplate White Grease is also good, it is used on the lower case of
Out-Board engines. I use clock oilers to pin point lubeing on my guns.
I also have an ultrasonic cleaner for parts and an Electronic Bore Scope.
All these things I used on Safe and vaults before I retired.

The Rem Oil contains Petroleum Distillate. The Hoppe's9 is a better oil.
It is a pure lubricant that will not gum, run or turn rancid. It will not
harm your stock when stored up-right and will prevent rust also.
