How can I repair a bad auto repaint job?

Optimus Prime transforms into a 1982 Kenworth K-100 semi-trailer truck, comprising three components. The truck's cab transforms into the robot mode of Prime himself, with vast strength and armed with a laser rifle. Within his chest is contained the mystic talisman known as the Autobot Matrix of Leadership (or Creation Matrix), carried by all Autobot leaders and passed down through the ages. The truck's trailer disconnects and transforms into the Combat Deck, a mobile battle-station/command headquarters with an "Auto-Launcher" robot armed with assorted artillery and beam weapons. It can also serve as radio antenna for battlefield communications between the Autobots. The Combat Deck can launch Prime's third component, Roller, a mobile scout buggy that can easily slip behind enemy lines; when Roller is present somewhere, it is as if Prime is there himself. Injury to one component is felt by each of the others, and while Prime could survive the destruction of either, despite the slight degree of autonomy they possess, the Combat Deck and Roller would not be able to survive without him.
