In view of the corrosion problem of modern Langdong chassis, a brand-new painting of automobile chassis every year can prevent the oxidation and aging of automobile chassis to the greatest extent. Chassis maintenance: 1. Chassis maintenance to prevent rust. The bottom of the vehicle is easy to get dirty and rust when passing through places such as stagnant water. Among them, the chassis, as the part closest to the ground, is most affected. In this case, it is recommended to clean and rust-proof the chassis.

Many car owners have the habit of putting coats on their cars, hoping to reduce the damage to the car surface caused by the external environment. In fact, when the weather is clear, it can resist dust, sunshine and acid rain, but once it is windy and rainy, "clothes" may bring more harm to the car. When the wind blows, the car clothes often seem to beat the car body under the action of the wind, causing damage to the car paint. In addition, if sand is blown into the car clothes, it will often leave countless tiny scratches on the car body, and such protection is often not worth the candle.
