If you are handy at all, tear the gun down and get a bottle of Oxpho Blue. This stuff does a surprisingly good job if you do your part to follow the instructions. If you are looking to create a "showpiece" this won't suffice, but it will protect a gun from any further oxidation and make it quite serviceable. If you must go elsewhere, Nu-Line looked pretty good to me when I was considering this.
