What to Do When the Car's Primer is Scratched?

Solutions for scratches on the car's primer: 1. If the scratch is not very noticeable, it can be repaired by waxing; 2. For deeper scratches, polishing can be used to remove them; 3. If there is denting after the scratch, it is necessary to go to a repair shop for panel beating and painting; 4. When the scratch exposes the primer, a touch-up paint pen can be used for simple primer repair. The car primer is the first layer of paint on the vehicle's body, serving to protect the body. It directly contacts the body, which is mainly made of metal, requiring the primer to have good anti-corrosion and anti-rust properties. Additionally, it must have excellent adhesion, both to the body and to the topcoat.
A few days ago, the primer on my car got scratched when I brushed against the curb while parked on the roadside, which was quite frustrating. The primer protects the car body, and if the scratch is left exposed, it can rust over time, making things worse. My approach was to first wash the car, clean the scratched area, lightly sand it smooth with sandpaper, and then apply a touch-up pen bought online that matches the car color. The touch-up pen is easy to use—just let it dry for a few hours—and costs only a few dozen yuan. For larger scratches, like from the door to the wheel arch, a touch-up pen alone won’t suffice, and partial repainting might be needed. However, I’d advise beginners not to attempt this themselves to avoid causing more damage. In short, addressing minor scratches promptly saves money and prevents rust, and being more careful when parking can help avoid such incidents.
