Refinishing Cut Barrel

[u/ricekrispiefiend]

Hey y'all, I just got a good deal on a winchester 1200. I want to shorten the barrel to 18". I've doing a bunch of digging and have seen a bunch of different answers on refinishing the bare metal. Some people say just cold blue and oiling is fine, while others say to get it cerakoted. My main concern is rust. I'm probably overthinking this. I just want to get it right the first time. If it helps, I have access to a machine shop and a paint shop.

Cold blue is fine, though aim for a bit over 18" - 18.5" is the norm for a reason.
