Automobile restoration is the process of repairing a car to return it to essentially the same or better conition than it was in when it left the factory at time of manufacture. It should include not only repair of the parts that can be seen – the body, the trim, the chrome, the wheels, the dash board and accessories and the passenger’s compartment – but the parts that are not necessarily visible or otherwise evident, including the engine and the engine compartment, the trunk, the frame, the driveline, and all ancillary parts like the brakes, accessories, engine cooling system, electrical system, etc. Besides repairs done to correct obvious problems, repairs are also done for cosmetic reasons. For example, even if a wheel is covered by a hub cap and not seen, and is structurally sound, it should have the tire unmounted, then any required repairs such as rust removal, straightening, priming and painting.
