How to remove scratches on the new X-Trail wheel hub?
2 Answers
X-Trail wheel hub scratch repair methods are as follows: 1. After most of the wheel hub is treated with dust-free sandblasting, use a finer water sandpaper for detailed sanding. 2. Once the wheel hub is sanded smooth, use alloy putty to fill in the scratches. This step is easy to understand, similar to using body filler in car body repair and painting. The wheel hub uses alloy body filler, which is harder and finer than the ordinary body filler used in car body repair. 3. Use an angle grinder to sand down any uneven excess. After the surface treatment is completed, it's time for painting. 4. If the wheel hub has a metal wire drawing process, conventional sanding is not suitable. A wheel hub wire drawing machine must be used for precision processing until all scratches disappear. 5. After the primer dries, apply a clear coat (topcoat, varnish, or gloss) for protection. Finally, bake in an oven at high temperature for 20 minutes.
I have some experience to share about hub scratches. Don't panic if you encounter scratches on your new X-Trail. First step is to thoroughly clean the hub: spray with dedicated hub cleaner, use a soft brush to remove dirt and grease, ensuring the surface is clean to clearly see the scratch location. For minor scratches, use 600-800 grit sandpaper with water to lightly sand the raised parts, avoiding excessive force that could damage the metal. After smoothing it out, evenly apply polishing paste, then polish to a shine either manually or with a small drill attachment. Finally, seal with a layer of car wax to prevent rust and stains. The full DIY toolkit costs just tens of yuan, and you can find all-in-one kits on Taobao. Suitable for superficial damage; for deeper scratches, you can buy filler putty to fill dents before treatment. For prevention, park away from curbs or stones to avoid friction. Well-maintained hubs enhance the car's visual appeal and extend lifespan, saving big money. DIY is cost-effective but requires patience and practice to avoid mistakes. The new X-Trail's hub material is easy to maintain, and regular care reduces issues.
