This Subaru bumper paint repair is fairly minor. Basically, the paint has just been scuffed off the wheel arch edge of the front bumper. It is actually more of a friction burn than a scrape, I see this type of repair regularly. Because the bumper is made from thermoplastic material mostly polypropylene and the panels are metal. Subsequently, the paint will come off the bumper but not of the panel. Basically, when the bumpers rub together the heat is transferred through the paint and melts just enough of the plastic to remove the paint. Alternatively, the paint is more tolerant of heat over the metal, Sometimes the panel will only need a light sand and polish to be restored.
Car parks are the most commonplace to receive damage like this Subaru bumper paint repair.
