What Are the Causes of Car Scratches?

[LaHarrison]

The causes of car scratches are: 1. Improper scrubbing during car washing may lead to scratches; 2. Excessive or mishandled polishing can cause scratches; 3. Scratches can occur when the car comes into contact with other vehicles, hard objects, roadside branches, or sand and stones while driving at high speeds. Methods to repair car door scratches include: 1. For hairline scratches, simply use polishing or apply a grinding compound to remove them; 2. For shallow scratches, applying toothpaste to the scratch can be very effective, especially for surface scratches that do not damage the car's primer; 3. For small dents not exceeding 5mm, fill with putty to level the surface, then proceed with touch-up painting. If the scratch exposes bare metal, first clean the surface of rust and welding residue, smooth it out, apply an anti-rust oxidizer, spray primer, and repeat the painting, drying, and polishing process to complete the repair.
