The key lies in the repair method - if done correctly, there won't be color difference. Here are three effective methods: 1. Toothpaste for scratch removal: When shiny car paint accidentally gets scratched, don't panic. First clean the scratch with water, then gently rub it repeatedly with a small amount of toothpaste until the scratch fades or disappears, then wipe dry with a damp cloth. This also creates a protective barrier against rust, especially effective for white car paint. 2. Nail polish for scratches: Similar to the toothpaste method, use nail polish matching your car's color. Apply evenly on the scratch and let it dry. The liquid polish fills the scratch and creates a barrier between the metal body and air, preventing oxidation and rust. 3. Touch-up pen: Ideal for small scratches and scuffs. First use ultra-fine sandpaper dipped in water to gently remove rust spots, always sanding in straight lines in one direction. After thorough cleaning, apply a base coat. For fresh scratches, clean and apply base coat directly. While not as effective as professional repair, this method prevents rust expansion for minor or inconspicuous damages.

My car got a big scratch last time, and after getting it repainted at the 4S shop, I noticed a slight color mismatch, especially obvious under sunlight. This is because the car's paint gradually fades and oxidizes with age, making it hard for new paint to match perfectly. However, the advantage of 4S shops is their use of original formulas and equipment, usually resulting in negligible color differences, far better than street shops. It's advisable to communicate your concerns with the technician beforehand, test a small sample, and after completion, don’t rush to leave—walk around the car to check under different lighting angles. For daily maintenance, remember to wash and wax your car regularly to protect the original paint, reducing aging and color mismatch risks, keeping your beloved car looking as bright and new as ever.

What Are the Main Raw Materials of Brake Pads?

The main raw materials of brake pads are adhesives, reinforcing fibers, fillers, and friction modifiers. Below is a detailed introduction about them: 1. Adhesives include resins and rubber powders: Their function is to liquefy and then solidify at high temperatures, turning the brake pad from powder into a solid block. 2. Reinforcing fibers serve as the skeleton of the brake pad: These include aramid fibers, steel wool fibers, copper fibers, mineral fibers, ceramic fibers, potassium titanate whiskers, etc. 3. Fillers: Different raw materials of brake pads have varying mesh sizes and diameters, requiring certain gaps to be filled. 4. Friction modifiers increase friction: These are materials harder than the brake disc, such as aluminum oxide, zirconium silicate, brown corundum, etc.

What are the components of the engine block assembly?

The engine block assembly mainly consists of the cylinder head, cylinder head cover, cylinder gasket, cylinder block, main bearing cap, and oil pan. Definition of the engine block assembly: The engine block assembly serves as the framework of the engine, providing the mounting base for the crankshaft connecting rod mechanism, valve train, and other major components of the engine's various systems. Classification of the engine block assembly: Features of dry cylinder liners: The outer wall does not directly contact the cooling water. Wall thickness ranges from 1 to 3mm. They offer good strength and rigidity but are more complex to manufacture, difficult to disassemble, and have poor heat dissipation. Features of wet cylinder liners: The outer wall directly contacts the cooling water. Wall thickness ranges from 5 to 9mm. They provide excellent heat dissipation, uniform cooling, and easier manufacturing. However, their strength and rigidity are inferior to dry liners, and they are prone to water leakage.

What does driving illusion include?

Driving illusions include light illusion, slope illusion, distance illusion, and curvature illusion. Light illusion: Strong sunlight mixed with the shade of trees on both sides of the road, alternating between bright and dark, can easily dazzle the eyes, creating a light illusion that leads to operational errors. In addition to sunlight, the glare from reflective objects, the strong light from high beams during night driving, and the glare from oncoming vehicles can all make it difficult for the driver's vision to adapt momentarily, causing a light illusion. Distance illusion: While driving on the road, drivers may sometimes misjudge the length of oncoming vehicles, the distance between vehicles during a meeting, or the following distance, leading to insufficient meeting distance or too close a following distance, resulting in accidents. When meeting another vehicle, no matter how great the speed difference between the two vehicles is, the meeting point always seems to be at the midpoint between the two vehicles.

What does it mean when the check light on the dashboard is on?

When the check light on the car dashboard illuminates, it indicates an issue with the engine's electronic control system. The check light is the engine malfunction indicator light. According to the driver's manual, when this light comes on, you should promptly take the vehicle to a 4S shop for inspection. Here are some common causes for the engine malfunction light to illuminate: Dirty throttle body or fuel injectors; excessive engine carbon buildup; leaks in the intake system, crankcase ventilation system, or secondary air system; clogged catalytic converter, damaged oxygen sensor; use of substandard fuel. Engine issues: Problems in the engine's electronic control system may affect normal engine operation. If the malfunction light turns off briefly but comes back on after driving for some time, it suggests an engine problem that requires timely inspection and repair.

What are the regular maintenance items at a 4S shop?

Regular maintenance items at a 4S shop include engine oil maintenance and brake maintenance. Engine oil maintenance: The replacement of engine oil and oil filter is mainly for the maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter functions to remove various impurities from the engine oil, ensuring the normal operation of the lubrication system. Brake maintenance: The car's brake system mainly consists of a vacuum booster pump, master cylinder, wheel cylinder, brake pads, and brake discs. Brake maintenance includes replacing brake fluid, brake pads, brake discs, etc. The brake pads and brake discs on the brake system are wear parts, and the brake fluid is a liquid that needs to be replaced regularly.
