Had the Mauser ready for cold bluing and just decided to leave the bare metal. I had ground down all the pitting and removed old bluing. Sanded down to 1500 grit and looks great. I know leaving bare steel is not good but I used lucas oil on every single inch of her. I will probably only shoot it once and then it'll become a wall hanger. I'll break it down to the smallest parts after shooting it and oil it up again and that will be it. If I choose to blue it, I can do that anytime. Using Lucas Oil gun oil to preserve the bare steel. It's a great product I've had success with in storing. It stays without gelling or gooping/evaporating. It was fun to tinker with.
https://www.theoriginalrusteprufe.com/ I have a friend in Texas that told me about this stuff. . Pretty thick but clear and would serve well in a wall hanger situation I believe. I use it on my gill gun, 54 cal BP and my Ak's cause they sit for longer periods of time and have had no issues with rust. It looks great !
Someone told me about this stuff when I was restoring my Nagant. It works great when you store them or shoot them
I had it ready for bluing. Sanded down to a 1500 grit and she was shining but then I kept looking at her and knew as few time that I might shoot her ( I will shoot it at least once) most of the time I'll be be looking at it on my wall. Sooooo I like the bare steel as well
