In order to check the scratches and scratch depth of the hub and whether the hub is about to break, the hub should be cleaned first. After cleaning the hub, dry it with a towel. Pay attention to wipe off the oil stain on the wheel hub surface with degreased waxing paper after cleaning, otherwise it will affect the painting! As long as the hub is not broken or deformed, it can be repaired.

After polishing the putty, we will repaint the wheel hub. But before painting, we'd better use waste newspaper to isolate the edge of the wheel hub to avoid liquid spraying on the tire. Then aim the hub spray at the putty coated in the previous step and spray it back and forth several times. In this way, the whole step of repairing the scratched hub is completed.

Because the scratch of the hub is very hairy, it must be polished flat. First use water sandpaper to polish the scratches, and then polish them repeatedly until smooth. Then evenly daub the putty, which can be daubed several times, with an interval of 5- 10 minutes each time, so that the putty can be fully dried.
