Apart from its aesthetic component, to which we pay the prior attention, the body of almost any car has a protective function. Therefore, it is the most important car part.
The modern cars are designed with the carrying body. It means that all mechanisms, systems and aggregates of the car are attached to the body. So, the body protects the internal car parts and acts as the frame.
The main causes of body damages are: the destruction of refinishing due to the long-term exposure to ultraviolet rays; corrosions that gradually destroy metal; different collisions that happen during the accidents.
The small damage of refinishing or little dents lead to the formation of rust destroying the body from the inside. It is quite difficult to find such things on your own, and when they can be seen from the outside, they are already not repairable.
