My Sig Sauer came with a small amount of Mil Comm TW25B. I like this oil because it comes out in a cream consistency and then spreads thin into a film. This keeps the application precise and not messy. However, I can't find it in any stores around here and its expensive online. I've heard that there really are no specific "gun" oils and that I can even use a motor oil. Do you guys know of where I kmight find TW25B and if this is true about using any oil? I just prefer nonliquid oils and I don't want something that gums up my gun either. Thanks.
