Owners can buy paint mending pens with appropriate color numbers by quoting their own car models and official color names. Generally, the price is about 40-50 yuan. Before use, the paint in the touch up pen shall be shaken evenly, and the primer shall be made up like nail polish. A certain diluent can be added into the touch up pen to spray out smoothly, and the position to be repaired shall be carefully sprayed. After the touch up pen is dry, fine wax can be applied.
Scratch on the primer

Generally, the bumper, rearview mirror and the wheel arch of some cars are made of engineering plastics, which will not rust. If you do not touch up the paint, it depends on the owner's requirements. But if these heavy scars appear on other parts of the car body, it needs to be repainted, otherwise even a small damage will start to rust on the steel plate. At that time, even repainting is difficult to rust. The owner can clean and dry the car first, apply rust remover on the scratches, wait 10-15 minutes to wipe the rust remover with face paper, to avoid further rust on the scratches.
