Okay, maybe rust bluing is not the way to go with my Gummint model, maybe I should simply re-parkerize it. My concern (I AM a worry worm) is can a once-parked gun be re-parked? I keep reading how parkerizing etches metal, how it removes base metal, and that should be taken into account for tolerances...
How many times can you re-parkerize a firearm?
