Home Forums Hunting & Shooting Gunsmithing Ever tried to do a cold rust blue at home ?

I've done the traditional slow rust bluing with good results but over the last few years I've used Mark Lee's Express Blue #1 ( no humidity box required ) with very good results. If you pay attention to what you're doing, you can't tell the difference between it and the traditional slow rust blue. It isn't a fast process but is less work than the traditional methods.
