Does Full Car Polishing Cause Significant Damage to the Paint?

Normally, full car polishing does not cause significant damage to the paint. If polishing is done only once or twice, it will not harm the paint much. However, frequent car polishing can damage the paint to some extent, as the paint becomes thinner with each polishing, weakening the protective ability of the car body. Car polishing involves grinding away imperfections and oxidized or aged paint on the car's surface. It also helps clean the body, effectively removing dirt and corrosion, restoring the paint's cleanliness. Polishing the car before waxing or sealing enhances the results and prolongs the effect. The car polishing process is as follows: Washing the car: Before polishing, the car must be thoroughly cleaned to remove dust particles and avoid secondary damage to the paint. Sanding: After washing, rough sanding is performed on the car body. Depending on the size of surface imperfections or scratches, different grades of wet sandpaper are used. Polishing: After sanding, a polishing machine and polishing wax are used for detailed polishing of the sanded surface. Mirror restoration: After polishing, a mirror-finish treatment agent is applied to restore the mirror-like effect of the car body, followed by waxing.
