I suppose I could go scrape some cosmoline off one of the mosins. . . nah, that stuff is NASTY.
Kroil is another product that is a rust inhibitor. Really great if you need to have something out in the open for a while and don't want any rust forming. DH learned about that working with Siemens Electric- replacing generators in an electric plant. He was operating the crane. They had to take the roof off the building to get them in and out.
They wanted to be extra careful nothing got any rust, so they drenched the parts with this.
