Does Car Polishing Damage the Paint?

[OValerie]

Car polishing does cause a certain degree of damage to the paint surface. The steps for car polishing and the criteria for determining whether polishing is needed are as follows: Steps for Car Polishing: Wash the entire vehicle, sand with water sandpaper, use a mechanical grinder (electric or pneumatic) with coarse polishing compound to rough grind the marks left by the sandpaper, then apply polishing compound for fine polishing, use a mechanical polisher with a mirror-finish treatment agent to remove swirl marks left by the coarse polishing compound, achieving a mirror-finish effect on the paint film, and finally perform manual polishing. Criteria for Car Polishing: Polishing is necessary for vehicles used between 4 to 5 years, or when there are multiple minor scratches on the car's paint surface, in which case the scratched areas can be polished.
