Why Can't Brushed Wheel Hubs Be Repaired by Painting?
2 Answers
Because the material of brushed wheel hubs is special, and using paint for repair cannot fundamentally solve the problem. Here is some relevant information about brushed wheel hubs: 1. Repair Methods: If the scratches on a brushed wheel hub are not severe, just minor scrapes, you can use sandpaper to polish them to a gloss similar to the original. If the scratched area is large, you can also use wheel hub-specific stickers, simply applying them directly. For serious scratches, it is recommended to go to a 4S shop or auto repair shop to use a professional brushing machine for better repair. 2. Maintenance Methods: Although scratches on the wheel hub do not significantly affect the safety of the car, they seriously affect its appearance. When there are stubborn stains on the surface of the wheel hub, it is advisable to use professional cleaning agents, which can gently and effectively remove the stains while minimizing damage to the aluminum alloy surface.
As someone in the auto industry, brushed alloy wheels cannot be repaired by painting because their surface features fine brushed textures created by machine grinding for a metallic finish. Applying a layer of paint would completely cover the texture, turning it into a smooth surface and losing the original sharp style of the car. Worse yet, paint has poor adhesion on brushed materials, leading to peeling or bubbling over time, which actually worsens the repair. The correct approach is to take it to a professional shop for re-brushing with specialized machinery or to perform localized grinding to restore the texture. For daily maintenance, avoid scratches from hard objects and keep them clean to extend their lifespan. Remember, wheels are the face of a car—haphazard painting can lower the vehicle's overall class and safety rating. Although the repair cost might be higher, it's a one-time fix that lasts.
