Scratched car wheel hubs can be repaired. First, assess the severity of the scratch. If it is severe, aluminum welding is necessary. For minor scratches, specialized aluminum alloy filler putty should be used. It is crucial to use high-temperature primer and topcoat specifically designed for wheel hubs, which must be baked at high temperatures. For deformed hubs, a shaping machine is required to check and correct any misaligned sections using gauges. For brushed finishes, a fully automatic brushing machine is needed. Wheel hubs are critical components, so avoid using body filler putty or low-quality paint for repairs, as they are prone to cracking and peeling. Methods for repairing scratched wheel hubs: 1. Inspect the damage. If the scratch does not reach the inner side of the hub, it can be easily repaired. Use paint thinner to clean the area around the scratch and remove dirt. 2. For deeper scratches where dirt is hard to remove, use a toothpick to thoroughly clean the area. 3. To avoid accidentally painting unaffected areas, carefully apply masking tape around the scratched area. 4. Prepare the brush tip and apply touch-up paint. Since the paint will shrink slightly as it dries, it is best to apply it slightly raised. 5. After painting, allow it to dry completely, which may take about a week. Once dry, use waterproof paper soaked in soapy water to smooth the surface. 6. After smoothing with waterproof paper, polish the area with a compound to restore shine, and then apply wax.

Oh, you scraped the car's chassis on a rock, right? I've encountered this situation many times. If it's just a minor scratch, like the surface paint being rubbed off, it can be completely repaired—just take it to a professional repair shop, clean it thoroughly, and apply a layer of chassis anti-rust paint. It won’t cost more than a few hundred bucks. If the scratch is deep and damages the metal frame, you’ll need to reinforce it with welding or by replacing small parts. Don’t underestimate it—if left unrepaired, rust can lead to leaks into wiring or the fuel tank, which could cause major trouble. Always drive carefully to avoid rough roads, and consider adding a rubber underbody guard for prevention. Safety first!

As an experienced driver, I know that chassis scratches are common minor issues and can definitely be repaired. First, use a lift to raise the car and check the size of the scratch: if it's shallow, just buy a can of chassis paint and spray it yourself; if it's deep, take it to a repair shop for a professional inspection. Ignoring it could lead to rust spreading and damaging the suspension or exhaust pipe, multiplying the repair costs. I recommend regularly checking the chassis during car washes, especially after rain, to detect and address issues early, saving both hassle and money.

The chassis scratch can definitely be repaired - don't delay. For minor scratches, purchase a chassis protective spray from auto parts stores for DIY treatment. Severe scratches require professional inspection with specialized equipment, potentially needing alignment correction or welding repairs. Leaving damage untreated allows moisture penetration that weakens the frame through corrosion, creating high-speed cornering risks. Remember to promptly clean off mud and debris after parking - prevention is key.

I've personally experienced this issue - the car scrapes its undercarriage when going over potholes, but it's definitely repairable. First, wash the car and clean the scratched area to assess the damage. Surface damage can be fixed by spraying anti-rust paint. If the underbody protection plate is cracked or the beam is deformed, replace the parts and polish them. Neglecting repairs can lead to serious consequences: rust may cause oil leaks or electrical short circuits, turning a few hundred yuan repair into thousands. Develop the habit of slowing down when encountering obstacles, and consider adding underbody armor for extra protection against scrapes.
