Reasons for small bubbles on car paint: 1. The paint film is sprayed too thick, or inappropriate hardeners or thinners are used; 2. Incorrect spray gun nozzle (aperture), spraying viscosity, or spraying air pressure; 3. Insufficient standing time before heating and drying or inadequate airflow in the paint booth. Car paint is a protective film sprayed onto vehicles, serving as a type of coating that makes the car body less susceptible to corrosion and enhances its aesthetic appeal, with different paints offering varying effects. The main characteristics of car paint performance include excellent film fullness, high gloss, high hardness, good adhesion, and superior mechanical properties.

Where is the ABS pump located in a car?

The ABS pump is located near the firewall in the car's engine compartment. The working principle of the ABS pump is: relying on highly sensitive wheel speed sensors installed on each wheel and the vehicle's speed sensor, under computer control, when emergency braking is detected and a wheel is about to lock up, the computer immediately commands the pressure regulator to release pressure from that wheel's brake caliper, allowing the wheel to resume rotation. The ABS pump, also known as the Anti-lock Braking System, features anti-skid and anti-lock characteristics. Its working process involves a cycle of locking and releasing, keeping the vehicle in a state of near-lock rolling, effectively overcoming issues like deviation, side-slip, and fishtailing during emergency braking, and preventing loss of vehicle control.
