Methods for Repairing Scratched Corolla Wheel Hubs
2 Answers
Methods for repairing scratched Corolla wheel hubs are as follows: 1. After most wheel hubs undergo dust-free sandblasting treatment, proceed with detailed sanding using finer water sandpaper; 2. Once the wheel hub is sanded smooth, use alloy putty to fill in the scratches. This step is easily understood, similar to using body filler in automotive sheet metal painting. The wheel hub uses alloy body filler, which is harder and finer than ordinary body filler used in automotive sheet metal; 3. Use an angle grinder to sand any uneven excess. After surface treatment is completed, proceed with painting; 4. For wheel hubs with a metal brushed finish, use a wheel hub brushing machine for precision processing until all scratches disappear; 5. After the primer dries, apply clear coat paint, varnish, or gloss oil for protection. Finally, bake in an oven at high temperature for 20 minutes; 6. The wheel hub repair process is essentially complete. To make the wheel hub look newer and more attractive, use a polishing machine with both coarse and fine polishing compounds for the final sanding.
Previously, the alloy wheels on my Corolla got scratched, and I found it quite fun to repair them myself. First, thoroughly clean the wheels, especially the scratched areas, and dry them with a soft cloth to avoid dust interference. Next, sanding is key: I chose 400-grit fine sandpaper, lightly wet-sanded the raised parts of the scratches, being careful not to press too hard to avoid deeper damage. For deeper scratches, apply a specialized wheel filler paste, let it dry completely, and then sand it smooth. Painting steps: spray a layer of primer evenly, let it dry for 10 minutes, then apply the topcoat, ensuring the color matches the original factory shade. After the paint dries, polish the surface either by machine or by hand to restore a mirror-like finish. Perform the entire process in a well-ventilated area and wear gloves for hand protection. I spent less than 50 yuan, and the result looked like new wheels. To prevent future scratches, park farther from curbs. DIY saves money and hassle while improving hands-on skills—I recommend starting with minor scratches to practice.
