You can use Eagle 1 Polish/Wax and it will remove those prints. I did a friend a favor on his 2006 FiveHundred it had finger prints all in the clear coat around the doors and the trunk lid. If the Polish/Wax does not do it I ended color sanding the truck to remove 4 finger prints but looks good now and his car was black they showed really easy. I guess with humidty Ford is not letting these cars dry enough before they finish building them. My friend probably purchased the only FiveHundred in Ohio and they are in a hurry to build them...lol... My dealer has 40 of them with rebates.
