I guess I really don't understand this need to stop the bluing process. Are you telling me that this is standard procedure on any blued barrel? I have had other blued guns and never seemed to see this phenomenon. If this were the case I'm surprised the customer support person at Knight didn't tell me that, or that they don't recommend some action to "stop the bluing process" in the manual.
I'm not saying you're not right,in fact I appreciate the input, I'm just surprised.
Thanks again,
