You could always get it cerakoted or nitrided. The nitride is about bullet proof but costs the most to do. I have several nitrided rifles now and they are practically impervious to weather. My 300 RUM is completely nitrided, after my moose hunt this year I forgot to take it out of the kolpin case right away and when I remembered a week later when I pulled it out there was water running out of the case. wiped it down and let it dry out, not a spec of rust.
