Will the paint chip on a car get bigger if left unrepaired?

[DeNaomi]

If the paint chip on a car is left unrepaired, the damaged area will indeed get larger. The car's paint surface naturally oxidizes over time, causing the paint film thickness to decrease until the underlying material is exposed. Causes of car paint chipping: Scratches or collisions; Issues during the painting process due to poor quality. This includes low spraying temperature, expired paint, excessive dust on the car surface, overly thick paint application, poor-quality primer, poor-quality putty, or inferior car body quality. Methods for repairing car paint: First, clean the area to be repaired with water. Use coarse sandpaper to smooth out any rough edges from the scratch, then use fine sandpaper to polish until smooth. After sanding, dry the area with a clean towel or paper towel. Apply an appropriate amount of putty to a spreader based on the size of the dent and fill the dent. For repairing dents on the bumper, first smooth out any rough edges. After sanding and cleaning, apply the putty. Even with regular maintenance or touch-ups, prolonged use of a car will inevitably lead to paint wear and aging. To restore the car's original glossy appearance, a full-body repaint is necessary.
