Wilson Combat does a very good video on friction tests of various gun oils. Ever since watching that video I only use Ultima-Lube II on all my guns.I saw that video a couple of months ago. I use FL and I was glad to see it did rather well in preventing rust. I would like to see a test on various cleaners and lubes that shows which product reduces friction and wear the best.
Well that's a lot of info to take in.On the carry guns, car wax on exterior, Lockease Graphite on the high friction areas. Al; greases thicken in the cold, and all oils evaporate/drip off/congeal. Waxes aren't lubes, but they prevent rust very well. Oils and solvents mess up waxes, so there has to be a "practice spare" gun that gets the wear and fouling of firing, the carry gun does not. Gotta have a spare, anyway, in case your "main' gun" is seized as evidence after an incident. If you have a "pending case", you can't buy another one, and if you've shot a homeboy, his buddies may well soon make you wish that you had a spare gun.
