Has anybody else tried Lubriplate 105?
White grease, comes in a 10-ounce tube, GM product.
We used a lot of it in the oilfield wireline business for cableheads, gun ports and things like that. Put a gun down to 3600 feet and you have just about 2000 pounds a square inch on it, nothing inside it and the sal####er outside trying to get in so it can P all over your Primacord and deaden your detonator dodo dead. Stuff doesn't displace even under that kind of punishment AND it doesn't freeze up in40 below, either.
I use it on slides, frames. US military recommended it for Garands in cold weather. Works fine.
If you have some that's really old, you will find that a bit of super-fine oil tends to separate from the remainder of the emulsion. This you hoard, as it is terrific for oiling tiny little parts with a single drop on the end of a pin: don't have to rip down your entire trigger group to lube it.
Worth a try. And it's not expensive.
