Should the Original Paint Be Sanded Off Before Repainting?

When repainting the entire vehicle, it is not necessary to sand off the original paint; simply pay attention to color matching for the original painted areas. Key considerations for repainting: Color Matching: During paint mixing, special attention must be paid to color differences. Protective measures should be taken, covering all non-painted areas with newspaper or other masking materials. Also, pay attention to spray gun pressure and working environment conditions. Baking Time: The spray path should maintain perpendicular alignment with the workpiece surface. The distance between the spray gun and the surface typically ranges from 15 to 30cm, adjusted according to the surface angle. For wetter, darker, and thicker coatings, reduce the distance; for drier, lighter, and thinner coatings, increase the distance. Spray Angle: The spray gun should maintain a right angle to the surface and move parallel during automotive painting. The gun movement speed should be consistently maintained between 30 to 60cm/s. Tilting the gun or using arcing motions with variable speeds will result in uneven paint thickness, causing streaks and blotches. Movement speeds below 30cm/s may lead to paint runs.

What is the China VI Standard?

China VI is the China 6 standard. The following is an introduction to China 6 vehicles: China VI: Full name: National Sixth Stage Emission Standards for Motor Vehicle Pollutants, which refers to the emission standards for vehicle exhaust. Currently, China is implementing the China 5 emission standard; the China 6 emission standard is 40%-50% stricter than China 5, comparable to U.S. standards, and can be considered one of the most stringent emission standards globally. The China 6 emission standard is implemented in two phases: China 6a and China 6b, with China 6b being stricter than China 6a. Implementation Requirements for China VI: According to national requirements, the China 6 standard is implemented in two phases. Starting from July 1, 2020, all light-duty vehicles sold and registered must comply with the "China 6a" limit requirements; from July 1, 2023, all light-duty vehicles sold and registered must comply with the "China 6b" limit requirements.

Are Side Curtain Airbags Effective?

Side curtain airbags primarily address side impacts while also providing some protection in certain offset frontal collisions. Here are the key details: How side curtain airbags work: When a side collision occurs, the actual gap between occupants and the door/B-pillar rapidly closes, creating a cushioning effect. Functions of side curtain airbags: During accidents, these airbags effectively protect occupants' lives by strategically deploying from optimal positions to counteract impact forces from various directions during collisions.

What to Do When Water Leaks into the Car Trunk?

Here are the methods to deal with water leakage in the car trunk: 1. Regularly clean the sunroof and trunk: During regular car washes, the sunroof and trunk are often overlooked. It is necessary to clean the drainage channels of the sunroof and trunk, wiping away dust and mud from both sides of the drainage channels. Use a slightly stiff wire or brush to unclog the drainage holes, then pour some detergent water for rinsing. 2. Lubricate and clean the sealing strips: Use a damp cloth to clean the sealing strips to prevent fine sand from sticking to them. Talcum powder or baby powder can be used to absorb excess grease and moisture from the sealing strips.

How Long Should You Warm Up Your Car in Winter?

Warming up your car for 1 to 2 minutes in winter is appropriate, allowing the engine coolant to reach normal operating temperature before driving. The reasons for warming up your car in winter and the impacts of not doing so are as follows: Reasons for warming up your car in winter: After prolonged parking, the engine oil flows back into the oil pan at the bottom of the engine; before the engine reaches its operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to low temperature; in cold conditions, gear oil flows to the lower part of the transmission. Impacts of not warming up your car in winter: Not warming up your car in winter can cause wear and tear to the engine, transmission, and various engine components, leading to reduced lifespan; it increases fuel consumption and makes the engine more prone to carbon buildup inside.

What is the difference between disc brakes and drum brakes?

Drum brakes and disc brakes differ in braking methods, composition, etc. The specific differences are as follows: Different braking methods: Drum brakes use hydraulic pressure to push the brake shoes against the inner edge of the brake drum, generating friction to inhibit tire rotation and achieve braking. Disc brakes have flat brake pads on both sides of the brake disc. When hydraulic pressure from the master cylinder is delivered to the wheel cylinder, the brake pads clamp onto the brake disc to achieve braking. Different compositions: Drum brakes consist of a brake backing plate, wheel cylinder, brake shoes, related linkages, springs, brake pins, and the brake drum. Disc brakes are hydraulically controlled and mainly comprise a brake disc, wheel cylinder, brake caliper, and hydraulic lines. Different advantages and disadvantages: Drum brakes have good self-braking effects and lower manufacturing costs, but their braking system responds slower, the pedal force is harder to control, they are less suitable for high-frequency braking, and they are harder to repair. Disc brakes offer better heat dissipation, simpler construction for easier maintenance, but the brake pads wear out faster, requiring more frequent replacement.
