I have a mid 70s 94 I picked up cheap...someone had (believe it or not) spray painted the entire gun, wood and all...with matte black Rustoleum.
I stripped all the metal. Anything blued was fine, but the reciever lost all its finish, leaving it a wonderful antique worn gray look. I like it very much and other than refinishing the wood, left it as is. I just waxed the reciever, and over the seven or so years I have had and used it the reciever is weathering just fine.
