Gunsmith question (blackening)
I have a little 20 gauge shotgun that has some rust on the barrel. It
is functional despite that, but I would like to clean it up a bit. I
would like to know what is the proper procedure. I guess I can remove
rust and even polish it a bit, but then I would somehow blacken the
barrel again. Is there anything that you would recommend for this sort
of thing. Thanks
