What are the methods for car paint touch-up?

[VanessaAnn]

Methods for car paint touch-up: 1. A touch-up pen can be used for small scratches. If the rust is not severe, you can first use very fine sandpaper dipped in water to gently remove the rust spots, but avoid sanding randomly without direction—always sand in straight lines in the same direction. After completely cleaning the area, apply a layer of primer. 2. Computer-mixed paint spraying method: Using computer-mixed paint ensures a more precise paint ratio and higher paint adhesion. After repair, the paint surface is less likely to peel due to air erosion, resulting in a better repair effect. Precautions for car paint touch-up: 1. If a section of the door needs touch-up, use the anti-scratch strip as a boundary and spray either the upper or lower half entirely. This minimizes the visibility of slight color differences. 2. If the original car paint is pearl paint, use imported paint for touch-up to achieve better results and stronger paint durability.
