Just could develop some surface rust over time. But if you keep your stuff super clean like most builders, you shouldn’t really have any rust problems. Some of my guns have a few bare metal spots from time time. And never had any appreciable rust! Another thing you can do it you are worried and can’t get cold blue, just pickle the exposed metal surface to vinegar, or smear some yellow mustard on it to induce a patina. But I wouldn’t worry.
