Can touch-up paint be leveled by polishing?

[McEleanor]

Touch-up paint cannot be polished because the applied paint lacks hardness and will simply come off during polishing. Below are detailed explanations: 1. Light scratches: For light scratches, prevention is key. It's best to protect the paint when it's still new. Apply a layer of mirror glaze to the car's surface. Mirror glaze primarily consists of high-molecular polymers and works directly on the paint surface. After cleaning the car body, use a polishing machine or manual operation to vibrate and press the mirror glaze into the paint, forming a protective net-like film that significantly enhances the paint's hardness. 2. Severe scratches: If the car's scratches have exposed the primer, localized repainting is necessary.
