I'd like to know what you use and why. There are so many gun oil products that there isn't enough space on one thread to list em all. Please don't bring WD-40 into the conversation, that sht doesn't belong on a firearm if yah ask me.
Some of the worst I've found so far was Rem oil in the aerosol can. I used to think it was decent, but it evaporates off, and doesn't protect the inner parts. It would leave white residue that would build up overtime. Not a good gun oil if yah ask me.
Lately I've been using the tetra fluoro-polymer oil but it smells bad. The tetra gun grease doesn't smell bad and I always use that on the rails of bolt guns and on other areas that see alot of heavy movement. The tetra oil is heavy, but does good in the cold weather too. In an emergency, I've used Sea Foam Deep Creep as a gun oil, and that too was good stuff, stayed thin in cold weather, and never evaporated off.
What do you use or don't use? Anything cheaper than gun oil that has worked good for you?
