I'm thinking that I have gotten lucky. At this point most of my rifles have been blued and I have never had an issue with corrosion including my crop damage rifle that had never been cared for gently. When I took it out the stock to send it in to be threaded there was a small line near the stock.
The picture of the Blued action after a few hours is really surprising to me, I would have been shocked to find my rifle like that.
Way back when I used to hunt in the rainforest with blued rifles I swear they would start rusting during the drive out there.
