When polishing automobiles, it is necessary to grasp the inclination angle of the polishing machine, polish smoothly, clean up the dirt on the polishing disc in time, and avoid unnecessary damage to the paint surface.

Car polishing is the process of car beauty, in the waxing, glazing or coating of the car first to do a polish. Because the glaze coating must be polished first, and it is a finely polished car before it can be made into a mirror. This is the operation that the glaze must go through.

Without polishing, the paint is uneven, and the glaze retention time is very short, and it cannot have the effect of long-term adhesion at all, which is no different from waxing.

Precautions should be taken for polishing:

For different polishing positions, you should pay attention to the force, and do not grind the paint through. {The corners and water chestnuts of the car are gently carried over, and these places are the easiest to show the bottom. Use a large towel to cover the front windshield, the wax will stick to the wipers when polishing and it will be difficult to clean.

When polishing, you should pay attention to the angle and self-protection techniques, do not let the residual wax fly to the face, especially the eyes, and drop it to the floor.

1. Clean the whole vehicle. Clean the whole vehicle with a paint cleaner with strong detergency, and when using the cleaning agent, you should avoid new scratches caused by particle dust in the grinding.

2. Water sandpaper grinding. For defects such as coarse grains, fine sandpaper marks, flow marks and other defects on the painted surface, wrap 600 water sandpaper in water in a small rubber liner before polishing, and gently polish it until it is smooth (note that it cannot be worn through the paint layer).

3. Coarse and fine grinding. Use a mechanical grinder (electric or pneumatic) plus coarse abrasive paste to coarsely grind the traces of water sandpaper; Then add abrasive paste to polish and polish fine grinding.

4. Polishing. A mechanical polishing machine is used to remove the spin marks left by the coarse abrasive paste with a mirror treatment agent to achieve the effect of mirror polishing of the paint film.

5. Hand glazing. After grinding and polishing, wipe off the grinding and polishing paste, immediately wipe all the polished parts with cotton yarn dipped in varnish wax, and then wipe off the excess varnish wax with dry cotton yarn to make the paint surface bright and dazzling.

Polishing is a method of automobile paint care, which is used to remove various foreign substances on the oxidized paint surface and car body, eliminate the subtle scratches on the paint surface, and deal with the slight damage and various marks on the car paint surface, so as to improve the mirror effect of the paint film and achieve the requirements of brightness, smoothness and showiness. A car that has been used for many years, after the wind and rain and the sun, the paint will inevitably be dull, and the polishing method can make the car paint quickly look new, and it looks as bright as a new car. Although polishing will make the paint thinner, it does not mean that the paint cannot be polished at all.

A small amount of polishing is the car paint can bear, for this reason, in the waxing, glaze, coating and other car paint maintenance process, it is inevitable to use the polishing process, but the number of times must not be too much.
