[QUOTE="ntsqd, post: 1975815, member: 93138"] Pulled a Savage OEM .22-250 barrel out of my storage container last weekend. I knew that it had a humidity problem, but I was still surprised to see spots of rust on it. Even 300 series rusts. Mostly because it was machined on and with ferrous tooling. Passivating removes the ferrous steel on the surface and increases the corrosion resistance of stainless steels. I'd start with stainless steel parts, after all mfging steps have them passivated per QQ-P-35, and then Cerakote or NiPTFE or NiB plate as appropriate. [/QUOTE]
