2. Check the corners that are prone to water accumulation: When driving on the road with water accumulation every day, sewage may remain on the automobile chassis, causing the automobile chassis to rust. For cars that have been used for a long time, sludge is easy to accumulate under the car, which needs to be cleaned by the owner in time, and the bottom corner of the door and trunk can not be ignored. These places are prone to water accumulation and need to be dealt with in time during the use of the car.

3, the use of car clothes should be reasonable: many car owners will cover the car clothes in order to better protect the paint surface, and the car clothes also have two sides, especially when it is windy and rainy, if the car clothes are blown into the sand, it will rub back and forth on the paint surface, which has a certain impact on the paint surface. Therefore, after the sandstorm, it is necessary to wash the paint surface with clear water and clean off the dust on the paint surface.

4. Clean up small rust in time: I can handle some small rust myself. If the rust is not serious, I can make up the pen. It should be noted that before treatment, I need to gently grind off the rust spots with very fine water sandpaper dipped in water. When polishing, I need to polish in the same direction, so that it can have a good effect when cleaning the rust. If I can't handle it myself, I suggest going to a professional repair shop or a 4s shop.
