This damage was caused by a steel gate, hitting the door several times. The factory paint and clearcoat are superior because the factory had the opportunity to bake the vehicle before the install the interior pieces. The final clearcoat is so well baked. It becomes a plastic hard substance layer over, the vehicles paint protecting it from all elements. This type of work can be done because of the elasticity of that clearcoat and how we can manipulate the metal and not crack the paint. These types of repairs are considered on the extreme level and capable technicians practicing the art of PDR can do this repair.
