Since it is polishing, polishing machine is inevitable. When the polishing machine was first controlled, the polishing machine would be disorderly because of uneven pressure. At this time, you need to accurately control the polishing machine and let it follow its own trajectory, instead of letting your arm follow the polishing machine.

2. The choice of abrasive:

There are many kinds of abrasives, generally divided into heavy cutting, medium cutting, micro-cutting abrasives, beauty wax, coarse wax, reducing agent and so on. According to the depth of scratches on automobile paint surface, judge the type of abrasive to be selected. If the scratches are too deep, it is necessary to re-cut and polish them into many tiny scratches, and then use micro-cutting to remove the tiny scratches.

3. Analysis of automobile paint surface;

There are many kinds of automobile paints, such as plain paint, metallic paint and pearlescent paint. Only by mastering the characteristics of various paint surfaces and then polishing them selectively can we achieve the best results.

4, car paint thickness judgment:

Generally, the outermost layer of car paint is transparent paint, and then colored paint. If you throw away all the transparent paint, the colored paint is called paint leakage, which is very troublesome and needs to be repainted. Therefore, when polishing, we must pay attention to judging the thickness of car paint. The thickness of car paint varies from department to department. Generally, German car paint is thick, while Japanese and Korean car paint is thin.

5. Treatment of scratches:

Judging paint scratches is also one of the most important skills. Mastering whether scratches can be thrown away is also a standard for a qualified beautician. Therefore, while polishing, you can try to scratch the scratches with your nails, feel the depth of the scratches on the car paint, and then judge whether the scratches on the car surface can be thrown away. If you hurt the primer and scratch the putty, you can't throw it away. )

6, grinder speed control:

Generally, the rotating speed of the polishing machine is 500-3500 rpm. At the beginning, the air can be pumped from the lowest level, which can better control the polishing machine and avoid paint leakage on the car paint surface caused by manual reasons.
