I will make a blanket opinion and leave it at that. I would never re-case color a gun. Once the colors are gone, there is no one in the world that can make it look as good as first applied. There is no replicating Colt, Winchester, Purdey, H & H or Boss colors once the horse has left the barn, even though there are many that do a good job (Turnbull). Let the gun show its age gracefully I say
