I have a Remingtonton 870 and I'm having problems with the metal rusting. I would like to refinish the metal before the rust gets out of hand for the time being I hit it with some fine steel wool I and keep it heavily oiled. I am trying to avoid bluing just cause I don't like the way it looks if that's what it comes down too in order to preserve the shotgun it is what I will do but I am hoping there is some good alternatives out there. I should also mention I use this gun regularly for hunting and skeet shooting. Thanks for the help.
