I just recently bought a 1990 Mercury Grand Marquis. It was obviously neglected. It has a lot of metal parts, such as chrome bumpers and metal trim around the windows and door. These are probably softer metals more like aluminum I guess. Besides the bumpers the rest of the metal has no shine. They are basically dull and have like a white glaze on them. I guess from age and neglect. I have tried one metal cleaner, but it is a very long and tedious job and I am not getting the results I want. Does anyone have any suggestions on what I should use? I was going to use a chrome cleaner, but not all the metal is chrome, but when cleaned should look like chrome. I am brand new to this forum, so I am hoping smeone out there could help me. Thanks
