Solution for exposed black primer on a white car: Use ordinary toothpaste to treat it by gently applying the toothpaste in a circular motion on the scratched area. After rain or washing the car, remember to reapply it. This can help reduce the appearance of scratches and also act as a simple barrier, preventing rust in the short term, especially for white car paint, where the effect is noticeable. If the area where the paint is scraped off is not large, you can repair it yourself by touching up the paint. You need to purchase a touch-up pen set of the same color code online, which will include all the necessary tools for touch-up, such as sandpaper, putty, and polishing compound. With such a touch-up set, the repair process won't take too long.

Don't panic when you find white paint scratched to reveal black primer. As someone who frequently repairs such cars, common causes may be the topcoat being scraped off to expose the primer layer. First, assess the damage size: minor scratches can be treated with a touch-up pen of the same color code—clean the area and apply carefully. For larger damages, overall sanding and repainting are necessary; otherwise, exposed metal may rust and cause worse consequences. The steps are: thoroughly clean off dirt, gently sand smooth with fine sandpaper, apply filler primer, then spray topcoat for optimal results. Professional repair, though more expensive, offers high restoration quality and can inspect other potential hazards on the body. Daily precautions like parking away from obstacles and regular waxing to prevent paint wear are essential for keeping your car beautiful and safe long-term.

Why Does My Car Smell Strongly of Gasoline When Starting?

The reasons for a strong gasoline smell when starting a car are: 1. Insufficient air intake through the throttle body, leading to incorrect air flow information; 2. Excessive carbon buildup in the cylinder combustion chamber and pistons, resulting in insufficient cylinder pressure; 3. Too much carbon deposits inside the engine, causing poor atomization of the air-fuel mixture; 4. Gasoline pipe leakage, forming sludge at pipe connections, with the odor entering the cabin through the air conditioning system. Solutions for addressing a strong gasoline smell when starting the car include: 1. Replace the rubber hoses of the gasoline vapor canister; 2. Tighten or repair gasoline pipe connections; 3. Repair or reinstall the fuel pump; 4. Avoid overfilling the fuel tank.

Strong Jerking Sensation When Shifting from Second to Third Gear in Automatic Transmission

Introduction to the causes of strong jerking sensation when shifting from second to third gear in automatic transmission: Transmission issues: The jerking sensation during gear shifts in an automatic transmission can be caused by dirty transmission fluid, oil pump pressure leakage, or internal clutch slippage. A detailed analysis of the transmission's data stream is required to pinpoint the exact cause. Shift solenoid valve problems: If the vehicle has reached 2 years or 60,000 kilometers, it is advisable to replace the transmission fluid. If the issue persists after replacement, the shift solenoid valves for second and third gears should be inspected. Engine oil passage blockage: The engine's power output, which affects the smoothness of gear shifts, is determined by the ignition, air intake, and fuel injectors. A decrease in air intake, weaker ignition, or reduced fuel injection can lead to insufficient power, resulting in a jerking sensation.

Do I need to wait for the traffic light when driving to the right front?

If it is a dedicated right-turn lane, you generally do not need to wait for the traffic light in this situation. Below is relevant information about traffic lights: Introduction: Traffic lights are signals that direct traffic flow. Classification: Traffic lights are divided into motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator lights (arrow signals), lane signals, flashing warning signals, and railway crossing signals. Light Colors: Initially, there were only red and green colors. Later, after improvements, a yellow light was added. The red light means stop, the yellow light means prepare, and the green light means go. The reason these three colors are used as traffic signals is related to human visual structure and psychological response.
