Not serious: If the rust is not very serious, it can be solved with touch-up paint. Use ultra-fine water sandpaper with water to polish in the same direction until the rust is removed. After cleaning, apply primer, wait for it to dry, then sand it with water sandpaper, and finally apply the small can of original paint that came with the car. This counts as rust prevention treatment. Serious: If the rust is severe, it is necessary to go to a 4S shop for repolishing and welding. During the sheet metal repair process of the side skirt, high-temperature welding is required, which will damage the anti-corrosion layer of the original car sheet metal.
