I used a aluminum polish in stick form that is applied on a electric bench polishing wheel . I works good if the metal isn't pitted, I guess I could have sanded out the pits and final wet sand with 1500 grit then re polish. Do you think with the paint on there will mess up the performance of the reception or sound quality ? The tube shields looked like dark olive drab color before I painted them, were those tin plated as well? If they were you mention polishing those , but arent those steel with tin plating ? I made sure that everything that had been painted still had a good ground.
