How to Repair Scratches on New Car Rims?

[SanPreston]

This makes it convenient to inspect all scratches, the depth of the scratches, and whether the rim is cracked, such as cracks or deformations on the rim surface. Before painting, use old newspapers to isolate the edges of the rim to prevent the spray from getting on the tires. First, use water sandpaper dipped in water to sand the scratched area, repeating the process until it is smooth. Then apply putty evenly, which can be done in multiple layers.

I also scratched my alloy wheels before and had good results with a DIY repair. First, sand the scratched area with sandpaper, gradually progressing from coarse 400-grit to fine 2000-grit, rinsing while sanding to avoid overheating. After smoothing, apply wheel-specific filler, level the dent with a scraper, and wait for complete drying. Then spray primer to enhance adhesion, followed by color paint after 30 minutes - apply 3-4 thin layers with 10-minute intervals between coats. Finally, spray clear protective coating to prevent scratches, and avoid washing the car for 24 hours. All tools can be bought on Taobao for about 60 RMB total - the key is to be patient and take it slow.
