To repair the skirt (side skirt) in this way, first use a sheet metal machine to pull out the sunken part, that is, pull out the ribs, then shape, polish, putty and smooth it, then spray a layer of granular glue on the skirt, and then spray paint. The price of a private paint shop is about 150-200. Pay attention to spray the whole skirt, don't spray the concave part, otherwise there will be color difference.
