If it is made of aluminum alloy, it cannot be repaired and will have to be replaced. If it's not obvious, forget it. Skirts refer to skirts installed on both sides of the car body, which are also equivalent to air dams and are used to reduce the airflow entering the bottom of the car from both sides of the car body. It has a certain turbulence effect and can significantly reduce air resistance under certain conditions. The dress is part of the body spoiler kit, beauty comes second. If properly installed, it can reduce reverse airflow when the vehicle is moving. Generally speaking, the side skirts are recessed and basically need to be repainted, repainted, or replaced before they can look as bright as new. At high speeds, the skirt is like the ground sucking the chassis, which greatly increases operational stability. It should be used with the front and rear spoiler skirts, so it is necessary to modify it. Disturbing the flow, the wind resistance caused by high-speed driving of the car can pass through the bottom of the car smoothly, without causing the vehicle to drift while driving. Some high-end cars, such as BMWs, have the function of actively correcting the route when driving at high speed. That is, if you are driving at high speed, the computer will record it. If the driving direction deviates due to airflow, the computer will automatically correct the direction. The method to solve the rust after repairing the dent in the car side skirt is as follows: 1. First, determine the material of the side skirt, whether it is plastic, iron or other materials; 2. If it is iron metal, it is usually coated on the top layer in the form of particles. In this case, the only option is to go to a repair shop for body painting; 3. If it is made of plastic, if it is not very strong, use a small hammer wrapped in a towel to carefully tap it to restore its shape. Plastic materials have certain shrinkage properties; 4. If the plastic material is damaged, it should be taken to a specialized technician for repair and then painted to restore its appearance.
