When a white car reveals black, this black color is the primer. Additional information: 1. The role of automotive primer: Automotive primer is the first layer of coating directly applied to the surface of the treated vehicle component, marking the beginning of the entire coating process. It is designed to have excellent adhesion to the substrate, good compatibility with the intermediate or topcoat layers above, and must also possess superior corrosion resistance, rust prevention, oil resistance, chemical resistance, and water resistance. 2. Requirements for automotive primer: Depending on its application area on the vehicle, automotive primer must exhibit strong adhesion to the substrate, good compatibility with subsequent intermediate or topcoat layers, along with outstanding corrosion resistance, rust prevention, oil resistance, chemical resistance, and water resistance. Naturally, the film formed by automotive primer should also meet mechanical performance standards such as hardness, gloss, flexibility, and stone chip resistance.

What are the methods for judging the quality of a car battery?

Methods for judging the quality of a car battery are: 1. Check the electrolyte level height of the car battery; 2. Measure the electrolyte density to determine the discharge level; 3. Test the discharge level of the battery. A car battery consists of plate groups, separators, electrolyte, casing, terminals, connectors, and filler cap. The working principle of a car battery is to convert chemical energy into electrical energy. Car battery maintenance methods: 1. Avoid parking the car in open parking lots for extended periods; 2. In winter, avoid multiple uninterrupted starts of the car; 3. Frequently charge the car battery; 4. Regularly clean the battery terminals and apply grease to protect the wiring harness.

Why is there a strange noise when braking in reverse gear?

It is normal to hear unusual noises when braking in reverse gear. Since the vehicle moves forward for 99% of its total mileage, the brake pads and discs wear predominantly in one direction. The brake pads contain metal components, which can develop metal burrs over time. When braking in reverse, these burrs come into contact with the brake disc, causing the strange noise. The steps for reversing an automatic transmission vehicle are: 1. Press the brake and shift to R gear; 2. Release the handbrake and check the rearview mirror or turn around to observe the intended reversing path; 3. Gently release the foot brake; 4. After reversing to the desired position, fully depress the foot brake and engage the handbrake; 5. Shift from R gear to N gear while pressing the foot brake; 6. Release the foot brake to complete the reversing process.

Is it necessary to replace the brake disc when changing brake pads?

Replacing the brake disc is necessary when changing brake pads. The steps for replacing brake pads are: 1. Remove the wheel of the brake; 2. Use a wrench to remove the brake caliper bolts and take out the brake pads; 3. Use a cloth to clean debris from the brake caliper; 4. Install the new brake pads onto the brake caliper; 5. Tighten the guide bolts and check the braking effect. The working principle of brake pads is that the car uses the friction between the brake pads and the brake disc, as well as between the tires and the ground, to convert the kinetic energy of the moving vehicle into heat energy through friction, thereby stopping the vehicle. The function of brake pads is to provide stable, sufficient, and controllable braking force, with good hydraulic transmission and heat dissipation capabilities, avoiding hydraulic failure and brake fade caused by high temperatures.

What is the method for cleaning a car's front grille?

Car front grille cleaning method is: 1. Use a neutral sponge and neutral cleaner to scrub the front grille; 2. After spraying detergent, use a toothbrush to scrape the fine parts. The car front grille consists of a painted backplate, chrome-plated outer frame trim, and mesh chrome-plated grille pieces. The working principle of the car front grille is to control the selective opening or closing of the blades on the grille and adjust the opening angle of the blades based on multiple sensor information inside the car and the external environment while driving. The functions of the car front grille are: 1. To deliver air to the engine; 2. To ensure sufficient external air is blown into the engine compartment to ventilate and cool the engine, radiator, and air conditioning components.
