Should I repaint the chipped paint at the edge of the car door from opening impacts?

[LeBrianna]

If the car door only has minor paint chipping that hasn't damaged the primer, the situation isn't very serious. In fact, leaving it untreated won't affect the normal use of the vehicle as it doesn't impact the paint's lifespan. It just looks slightly unaesthetic upon close inspection, and can be covered with a car sticker. Below are relevant introductions: 1. Touch-up pen: For minor scratches on car doors, a touch-up pen can be used for repair. The purpose of using a touch-up pen is to prevent rust formation on the door. However, touch-up pens have certain drawbacks - they can't restore the car's scratches to a perfectly smooth finish. After the touch-up paint dries, the car's surface may appear uneven with a very rough paint texture. 2. Paint coating: If you want to protect the paint surface from damage, you can opt for paint coating. This involves applying a thin film over the car's paint surface to maintain the glossiness of the paint while also providing protection.
