I still think you got the wrong stuff. Lubriplate does have a product for firearms (if you can believe Brownells, and I see no reason not to because they have no motive to lie about it). But it's not the one you bought.

This is what I use. I apply it to rails and barrel locking lugs with a toothpick, not a tongue depressor.The Original Military Grease For Semi-Auto Rifles
Selected by the U.S. Military to lubricate M1 Garand and M14 battle rifles. A waterproof blend of mineral oil, calcium and zinc oxide that has a high affinity for metal so it stays put in all weather conditions, and lubricates even after the carrier begins to break down.
