Water spots, also known as water marks, typically appear as ring-shaped white spots on the car paint surface. The cause of this phenomenon is that water droplets, including rainwater and dew, can mix with pollutants in the air and dry on the paint surface. If the car owner does not promptly clean these spots, water spots may appear. Generally, these water spots do not cause significant damage; they usually only appear

Corrosion beneath the automotive paint film can be caused by external damage, including: 1. Gravel and stones striking the car during driving, damaging the auto paint film and eroding the metal layer, leading to gradual corrosion beneath the paint film. 2. The metal surface may have been directly touched by hands after pretreatment or may still have accumulated contaminants such as chemicals, sanding water, or pain
