I use RIG for storage and red bearing grease for my Garands, LRB M14, and a couple of M1 carbines. Incidentally, the latter is what I was advised to use in the CMP Garand class as well. Someone over there went through the trouble of replacing the original grease in the yellow top grease pots with the red stuff, leaving no trace of the original grease. Kudos to them for recycling/reusing those grease pots. Lubriplate gets rave reviews because it was used by the military. A primary reason it ended up as the choice Uncle Sam went with was how well it adhered, as opposed to lubricity or rust prevention. And that makes sense to me. If you've ever sprayed Gun Blaster in the op rod channel of a Garand that's been lubed with Lubriplate and didn't first wipe it away with a rag, then you know just how well that stuff sticks. Gun Blaster will melt away RIG in a heartbeat and bearing grease is somewhere in the middle. There's no shortage of grease choices. I stopped using RIG as a lubricating grease because Alabama summers have a way of turning it into "rust inhibiting oil." Plus I was getting little specks of it splattered on my face with the action cycled but that had more to do with my applying too much vs. it melting. When it comes to grease all that's needed is enough that you can see its sheen. Get a pint each of red sticky bearing grease and RIG and you're set for life.
I have a little jar of Brownell's Action Plus- a moly lube. Again, more grease and oils than I can go through in a lifetime.
For the ultimate in rust protection, there's Brownell's Rust Veto- a modern iteration of Cosmoline- and it smells awesome, just like the original! I greased up a couple of USGI M14 mags years ago and put them in storage. After degreasing them not several months ago, there wasn't a spot of rust anywhere to be found. However, neither was there a spot of rust to be found on any of the ungreased mags that were in use over that time. And in actuality, the attempt of greasing and storing them wasn't any test of Rust Veto's rust preventative properties, but a poorly designed experiment on my part to see if RV would impart any greenish hue to the parkerization on the mags (a topic for a completely different thread by the way).
Now that I think of it, I also have a tub of green bearing grease. I wonder if you go into a gun store in New Mexico and ask for gun grease if they ask, "Red or green?"
