I agree with the bare metal. But don't limit it to the starting system. To make your 6 volt system perform like it is supposed to, clean every ground and wire connected to it. Your car (and the wire) is 85 years old. Time and its friends, rust corrosion, wear and depreciation have all taken a toll on the car. Returning it to the way it was, when new, will make it work like new.
