A panel beater is a term used in some Commonwealth countries to describe a person who repairs vehicle bodies back to their factory state after having been damaged (e.g., after being involved in a collision). In the USA and Canada, the same job is done by an auto body mechanic. They do this using many skills such as planishing as well as various other metalworking techniques, welding, use of putty fillers, and many more. Accident repair may require the panel beater to either repair or replace various parts of a vehicle. These parts may be made from various metals including various steels and alloys, many different plastics, fibreglass and others.
