Auto accident repair is repairing a damaged automobile after it has been involved in a collision. The process can be divided into two steps: assessment and repair. The assessment step involves identifying the damage to the vehicle and estimating the cost of repair. This is often done by an estimator, who will then estimate the cost of repairs. The repairing step may involve one or more auto body technicians repairing individual parts or panels, such as bumpers, fenders, doors, hoods, etc.
