How to repair a small chip on the wheel hub?

[MacTessa]

Methods to repair a small chip on the wheel hub: 1. Use fine-grit sandpaper to smooth out the details, then fill the scratch with alloy putty after leveling; 2. After filling, use an angle grinder to re-sand any remaining uneven parts; 3. Once the surface is treated, apply paint. If the surface has a metal-brushed wheel hub, use a wheel hub brushing machine for precision processing; 4. After the primer dries, apply clear paint for protection and bake it in an oven at high temperature; 5. Start the polishing machine and use both coarse and fine polishing compounds to sand the wheel hub. The wheel hub is the rotating part of the tire's inner rim connected to the wheel core via spokes, i.e., the metal component that supports the center of the tire mounted on the axle, also known as the rim, steel ring, or wheel.
