What is the purpose of car polishing?

Car polishing serves the following purposes: For vehicle paint surfaces that have oxidation, dullness, or scratches, it can remove oxides and corrosive substances, thereby restoring the cleanliness of the paint surface. Car polishing refers to the processing method that utilizes mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece, achieving a bright and smooth surface. Polishing does not improve the dimensional accuracy or geometric shape precision of the workpiece but aims to obtain a smooth surface or mirror-like gloss. Sometimes, it is also used to eliminate gloss. Polishing wheels are generally made of multiple layers of canvas, felt, or leather, clamped on both sides with metal discs, and the rim is coated with a polishing agent uniformly mixed with fine abrasive particles and grease.
After driving for over a decade, I've realized that polishing isn't just about aesthetics—it thoroughly removes the oxidized layer and those annoying fine scratches from the car's paint surface, restoring its original shine, like giving the car a deep cleanse. After polishing, the paint becomes smooth, preventing water from pooling and dust from sticking, effectively protecting the paint from acid rain or UV damage. I believe regular polishing can make waxing or ceramic coating last longer; doing it once a year is sufficient. Occasionally using polishing paste for a light touch-up also works well—it's hassle-free and prevents rust. This maintenance method is simple yet effective, extending the car's lifespan and reducing the need for major repairs later. It's truly a practical investment.
As a car enthusiast, I always strive to keep my beloved car in top condition. The key role of polishing lies in enhancing visual appeal and protecting the paint—it eliminates marks and oxidation areas caused by daily wear and tear, making the car shine like new. I've found this particularly valuable when selling the car, as a refreshed appearance can significantly increase its valuation. After polishing, applying high-quality wax creates a more durable protective layer, reducing the hassle of frequent car washes. I've also noticed that in high-temperature environments, it provides better protection against sun-induced aging, making the investment pay off quickly overall. With just a few simple steps, keeping the car looking youthful is incredibly cost-effective.
