The treatment methods for severely scratched wheel hubs are as follows: 1. First, clean the wheel hub: Thoroughly clean the wheel hub (I removed the wheel hub for easier handling, but it's also fine to leave it on). After cleaning, dry it with a towel, making sure to wipe off any grease on the surface, as this can affect the painting later! Removing the wheel hub also allows you to clean off the considerable amount of metal shavings and stone debris on the wheel. 2. Smooth the scratched area of the wheel hub: Since the scratched areas are rough, they must be smoothed with sandpaper, using 150# sandpaper for this step. After smoothing (check by hand to ensure it's even), apply putty (wheel hub filler) evenly to the scratched area (ensure the grooves are filled), and wait for the putty to dry! Then continue smoothing with 320# and 800# sandpaper, making sure it's very smooth. 3. Apply paint and clear coat: After the above steps are completed, you can proceed to paint. Before spraying, cover the tire and any parts that don't need painting. Then spray evenly (note: spray in multiple thin layers, waiting for each layer to dry before applying the next, to avoid runs or sagging. After the wheel hub paint dries, finally apply a clear gloss coat.

When wheel rims are severely scratched, I previously tried repairing them myself. Gently sand the surface scratches with fine sandpaper, then clean off the dust, and spray on rim-specific primer and topcoat, preferably matching the original car color. If the scratches are deep but there's no deformation, with some effort, this method can restore 80-90% of the appearance. DIY kits available online for just a few dozen yuan can get the job done, just make sure to work in a well-ventilated area. However, if the rim edge is bent or chipped, attempting a DIY fix might worsen the problem. In such cases, it's safer to seek professional repair services—they have the tools to correct deformations and apply coatings, with costs around a few hundred yuan being reasonable. Additionally, rim scratches aren't just a cosmetic issue; long-term neglect can lead to tire imbalance, causing a bumpy sensation at high speeds. Remember to park farther from curbs—small habits prevent big troubles. Regularly washing the rims also helps reduce corrosion damage.

For severely damaged rims, I recommend prompt treatment, especially for aluminum alloy ones which are easier to repair. Professional shops will use a lathe to grind off the damaged layer, re-level the surface, and apply anti-rust paint, starting from around 100-200 RMB. Don't underestimate scratches - if a deformed rim isn't repaired, you may experience steering wheel vibrations or uneven tire wear while driving, compromising safety and driving experience. DIY options like sanding and painting only suit minor scratches; deep damage should be left to experts for security. When choosing a service, check reputation to ensure weather-resistant materials are used. For rim maintenance, wiping with a soft cloth after car washes preserves shine and reduces minor scratches. Long-term parking in humid areas may accelerate rusting, so don't neglect routine care. Timely treatment extends rim lifespan.

Severely scratched rims should not be ignored as they pose hidden dangers. I've seen a friend's rim dented from impact, causing unstable wobbling at high speeds. Deep scratches or cracks may compromise structural integrity and increase the risk of tire blowouts. During inspection, gently rotate the tire by hand to check for roundness. Scratch treatment: minor ones can be sanded down yourself, while severe damage warrants professional repair or replacement. Alloy rims have good repairability, but don't delay to prevent worsening issues. Safety always comes first—post-repair dynamic balancing tests ensure smooth operation. Similar tire issues also require early prevention.

What do Audi 35, 40, 45, and 55 mean?

Audi 35, 40, 45, and 55 indicate the horsepower of the engine. Here is an introduction to Audi's engine knowledge: 1. Meaning of the numbers: 35 generally refers to 1.4T, 40 generally refers to the low-power 2.0T, 45 generally refers to the high-power 2.0T, and 55 generally refers to 3.0T. These numbers represent the G-value, reflecting the car's acceleration. The larger the value, the higher the horsepower and the better the performance. 2. Supercharged engine: In 2008, Audi first introduced a supercharged engine—3.0TFSI, which was equipped on the 2009 A6L (C6PA). Since then, the 'T' in TFSI is no longer purely turbocharged.

Does Parking for a Few Minutes Count as Electronic Illegal Parking?

Electronic surveillance cameras consider parking for more than five minutes as illegal parking, while parking for less than five minutes is not considered illegal. Currently, the working procedure of electronic cameras for capturing illegal parking is as follows: when a vehicle enters a no-parking zone, the camera automatically takes a photo. If the vehicle leaves within 5 minutes, this photo will be automatically deleted. If the vehicle remains parked illegally for more than 5 minutes, the camera will take a second photo and upload it to the system, resulting in a penalty for illegal parking. Vehicle owners should note that in areas where parking is prohibited, regardless of the duration, stopping the vehicle will be captured and considered illegal parking. Locations where parking is not allowed include: Intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and sections within 50 meters of these locations. Road sections with no-parking signs or markings, areas with barriers separating motor vehicle lanes from non-motorized vehicle lanes or sidewalks, pedestrian crossings, and construction zones. Bus stops, emergency service stations, gas stations, fire hydrants, or within 30 meters of fire stations, except when using these facilities. In addition to parking in prohibited areas, reverse parking is also considered illegal. According to Article 63, Section 5 of the "Regulations for the Implementation of the Road Traffic Safety Law": when temporarily parking, vehicles must not be parked in reverse. Even if parked within a parking space, reverse parking is considered an illegal parking act.

Is it necessary to opt for the magnetic ride control suspension on the CT5?

Yes, it is necessary. The Cadillac CT5's magnetic ride control suspension demonstrates excellent support capability in corners, effectively suppressing body roll. The near-perfect body posture provides the driver with enhanced confidence. Additional information: 1. Advantages of magnetic ride control: The system features a simple structure, extremely low power consumption, a wide range of controllable stress, and enables instantaneous and precise damping force control. It is also insensitive to impurities, operates within a broad temperature range (-50°C to 140°C), and can be powered by standard low-voltage sources (such as regular car batteries), eliminating the hazards and inconveniences associated with high-voltage systems. Compared to traditional automotive shock absorbers, it significantly reduces moving parts, minimizes collisions, and thus operates with low noise. 2. Function of magnetic ride control: Vehicles equipped with this system can maintain increased tire-to-ground contact even on the roughest terrains, reduce tire rebound, and control the vehicle's center of gravity shift and pitch/roll movements to ensure stability. It also effectively manages body sway during sharp turns or evasive maneuvers.

How to Deal with Water Accumulation in the Car Caused by Magotan Sunroof Leakage?

After being exposed to rain, the sunroof of a Magotan may lead to water ingress into the car, which can have a significant impact on the vehicle. The specific details are as follows: 1. In severe cases: The electronic modules inside the car may be soaked in water. If not handled promptly and properly, it can corrode the wiring, plugs, and internal circuit boards, leading to vehicle alarms and functional failures. In such situations, avoid turning on electronic devices if possible. Use the mechanical key to open the car door and call for a tow truck immediately to send the vehicle to a repair facility for treatment. 2. In less severe cases: If there isn't a large amount of water accumulation on the floor mats, it is recommended to remove the vehicle's battery to prevent electrochemical corrosion, which could worsen the rusting of modules and plugs. Then, take out the floor mats, seat covers, etc., from the car, remove them for cleaning and drying to prevent odors later on. After drying, it is advisable to perform a comprehensive disinfection of the car. Rainwater soaking can breed many germs, so disinfection is necessary. Regular car use precautions: Always ensure the windows are closed before leaving the car, and make it a habit to close them properly.
