I've got an old Winchester 130 that I inherited from my grandad thats got a reasonable amount of rust on the barrel (he carried it around on the tractor and never really took care of it). Anyway, what's the best way to make this rifle look normal again? (the barrel anyway...lets not get started on the stock). I know I should sand or wire brush the rust off, but how do I fix the bluing? Sorry if this is a dumb question, but I'm new to anything remotely related to gunsmithing.
