Well since were talking about lubes, I'm finally put in my .02. First I agree for general use the CLP's can't be beat. But for extreme environment (cold or lots of rounds or dusty) I also use Krytox, which is made by Dupont...and NO I don't work for them. I wipe the gun and parts dry, then it only takes a little teeny bit wiped on bearing surfaces to lube well. It doesn't attract dirt, solvents don't dissolve it, and when you're gun is really dirty, you just wipe off the dirty stuff and put the clean on.
Even though this stuff was developed for the space program, I used it in Indianapolis and Formula One race car development. It has a higher and lower operating temp than petroleum based lubes, and you only need about a third of what you would normally use, for instance in a wheel bearing or other application.
They tried to use some of the less vicous formula for motor oil, but a car blew an oil line during development, and they had to shut down the track for hours and hours to get it off, and you sure can't do that during a race.
It comes in several types, including grade 205 which has a rust inhibitor. It's realy expensive though, so you don't see much of it around. But, I can put some on any gun and realy feel the difference.
That's a pretty good sales pitch, eh..?? I even used it before to quiet down my instrument panel where it was squeeking over bumps, and a inner door trim panel which made a scuffing noise. But like I said, for every day range sessions, I usually just do the CLP shuffle.
