How often should a car be polished?

[McGiselle]

Generally, polishing once a year is sufficient, or it can be determined based on the actual condition of the car's paint, as polishing can significantly damage the paint. The methods for maintaining car paint are as follows: 1. Car washing: This is a maintenance method adopted by many car owners and is the most basic method. Whether parked or driven, the car body will inevitably accumulate some dirt. The composition of this dirt is complex and may contain acidic corrosive substances, which can cause some damage to the paint over time. Therefore, regular car washing can help protect the paint. 2. Waxing: This involves applying a layer of wax to the car's paint surface and then polishing it. Waxing helps prevent oxidation, isolate static electricity, and enhance the brightness of the paint surface. It effectively separates the paint from dust and harmful gases, thereby protecting the paint. 3. Coating: This involves applying a high-molecular film with good hardness and smoothness to the car's surface. This film solidifies directly on the vehicle's surface, meaning the paint is directly protected by this film. Even minor damage will not affect the paint surface.
