Are the bumpers replaced at 4S stores the same as the original ones?

The bumpers replaced at 4S stores are the same as the original ones. The function of a bumper is to absorb and mitigate external impact forces to protect the safety of the front and rear parts of the vehicle body when the vehicle or driver is subjected to collision forces. The bumper is made of plastic, consisting of an outer panel and cushioning material, with a U-shaped channel formed by stamping cold-rolled thin steel sheets about 1.5 mm thick. The outer panel and cushioning material are attached to the crossbeam, which is connected to the vehicle frame's longitudinal beams with screws, allowing it to be removed at any time. The methods for repairing bumper scratches are: 1. Apply toothpaste to shallow scratches and wipe counterclockwise with a soft cotton cloth; 2. Spray a car paint scratch repair agent onto the scratches and wipe with a towel; 3. Use a touch-up pen to spray and fill the damaged area along the direction of the scratch, then apply fine wax after it dries.
