I like what you guys are saying: I'll leave it as-is. I'm not so much concerned about how this thing looks, more about how the cold blue job will hold up to moisture. I do take good care of my guns, but I've definitely have experienced rusting of guns after just a day in the field.
Good choice.
Regarding the rust issue, pickup a can of Ballistol and rub your weapons down from time to time and that'll be the last you see of rust.
