Steps for repairing scratched car wheel hubs: 1. Clean the wheel hub to facilitate inspection of all scratches, scratch depth, and whether the hub is cracked. If the hub surface has cracks, deformation, or is completely broken, it cannot be repaired. Only hubs without cracks or deformation can be repaired; 2. After cleaning, use degreasing wax paper to wipe the hub clean; 3. After leveling the putty, repaint the hub. Spray the hub coating onto the applied putty, gently spraying back and forth a few times to complete the entire scratched hub repair process; 4. The scratched areas of the hub are rough, so use fine sandpaper to smooth them out.
Last time my car's wheel rim got scraped against the curb, and the scratches were quite deep. The repair process actually involves several steps: first, remove the wheel rim and clean it thoroughly, then sand the scratched area with sandpaper from coarse to fine grit. For particularly deep dents, fill them with alloy putty; after drying, perform fine sanding again. Use special wheel rim paint to spray two or three even coats, making sure to choose the matching metallic paint color code. Finally, spray a transparent clear coat for protection, and using a heat lamp to dry it yields the best results. The entire process takes about six to seven hours. Doing it yourself can easily result in color mismatch, so I recommend spending three to four hundred to have it professionally handled for a more reliable outcome.
I've repaired wheel rim scratches three times, and my experience is: minor scratches can be covered with a wheel rim repair pen, but deep scratches require tire removal for proper repair. First, clean the grease from the wheel rim surface, then use an angle grinder with a sanding disc to smooth out the scratched area—this step is crucial! After that, apply a specialized wheel rim filler, wait for it to cure, and then finely sand it with wet water sandpaper. When spraying primer and color paint, apply thin layers with 10-minute intervals between each, and finish with a clear coat. The whole set of tools can be bought online for around 200 yuan, but patience is key.
