Polishing is a frequently involved procedure in automotive detailing, and selecting a good polishing product is crucial when dealing with damaged car paint surfaces.

There are several reasons why a painted surface may require polishing:

1. Adhered contaminants (such as dust, iron particles, etc.) can cause scratches and damage to the paint surface.

2. UV rays can cause paint fading, leading to a loss of glossiness.

3. Orange peel effect, characterized by an uneven texture resembling the skin of an orange, can occur on repainted surfaces, resulting in light diffusion and reduced glossiness.

4. Paint surfaces can be scratched by hard objects, leaving visible marks.

When scratches or marks appear on the paint surface, it is often challenging to remove them manually. Professional detailing shops need to perform grinding and polishing operations to effectively eliminate them. It is important to note that the normal thickness of car paint ranges from 120 to 150 micrometers. With frequent polishing, the paint thickness gradually decreases, and the duration of the natural glossiness of the paint surface also diminishes. Therefore, it is crucial to exercise caution when selecting grinding materials for your beloved vehicle.

Polishing the paint surface of a vehicle is a critical step in automotive maintenance and restoration. The process of polishing involves using specialized products and techniques to refine the surface, remove imperfections, and restore the paint's luster and shine. Understanding why the paint surface needs to be polished is essential for car enthusiasts and professionals alike.

One of the primary reasons for polishing the paint surface is the presence of contaminants that adhere to the surface over time. Dust, dirt, road grime, and iron particles can accumulate and embed themselves into the paint, causing scratches and swirl marks. These blemishes not only detract from the appearance of the vehicle but can also weaken the paint's protective barrier. By carefully polishing the surface, these contaminants can be safely and effectively removed, restoring the smoothness and clarity of the paint.
