Polishing is not as regular as car maintenance, and there is no specific mileage and time interval to determine whether it is time to do polishing again.
So polishing, or to look at the car specifically, although the mirror effect is great, but polishing will inevitably make the car paint thinner, so the car can not be often polished or anything, according to the need, such as a little scratch, there are foreign objects on the body, to eliminate the subtle scratches on the car, remove the oxidized paint, etc.
Car polishing is generally done in the car beauty shop, belongs to car beauty, in the car waxing, glaze, coating, will do a polishing of the car, because this is the process requirements, without polishing, the glaze holding time will be very short, not at all long-term adhesion effect.

The steps for grinding and polishing are as follows:
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.
In order to make up for these defects, grinding and polishing are usually carried out after spraying, so as to improve the mirror effect of the paint film and achieve the requirements of brightness, smoothness and showiness.
Extended information: Car polishing is the process of car beauty, in the process of waxing, glazing or coating, first polishing the car. 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. Of course, according to the situation of the car paint, polishing does not have to be done in all three steps, and new cars often can be restored in one step.
However, the car that has done coarse wax must be polished with medium wax, and the car that has done medium wax must be reduced with fine wax.
At present, the market demand for automobile polishing is very large, but the first aspect is slightly insufficient, especially with core intellectual property rights, there are not many enterprises with excellent product quality, and the industry as a whole lacks brand effect. In the stage of strong demand, there is no doubt that the industry demand is huge and the development prospects are good.
However, how to maintain the health, stability and sustainable development of the industry requires the joint efforts of enterprises in the industry, especially the need to give full play to the fastidious research and development spirit, further improve the production process, reduce costs, truly solve the practical difficulties of customers, strictly control the quality, and provide the most reliable products.

In order to maintain the brightness of the paint and enhance the hardness of the paint, it needs to be done once or twice a year, and frequent polishing is not good for the paint. Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and flat surface.
New car polishing and gold plating, in order to maintain the brightness of the paint, enhance the hardness of the paint, it is recommended to do it once or twice a year, frequent polishing is not good for the paint.
Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and flat surface. It is the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. New cars do not need to be polished within a year.
In the open air, the new car will be waxed in about two months, and the new car will do a good job of waxing on a regular basis, so that the paint can be well protected, and the good condition of the car surface can be maintained for a long time. These belong to car beauty, and the role of waxing is first of all waterproof, acid-proof rain, due to the protection of car wax, the amount of water droplets attached to the body will be reduced, the effect is very obvious, can reach 50% to 90%; The second is to prevent high temperature and ultraviolet rays, the weather is getting hotter and hotter, and it is easy for the car to be driven or stored outside all year round due to the aging and fading of the car paint due to light. Polishing refers to the surface of the car after spraying, there may be coarse grains, sandpaper marks, flow marks, white, orange peel and other small defects on the surface of the paint film, in order to make up for these defects, usually after spraying the grinding car polishing treatment, in order to improve the mirror effect of the paint film, to achieve the requirements of bright, smooth and gorgeous.
The main purpose of sealing glaze is to prevent oxidation of car paint, but these two methods can not solve the problem of oxidation of car paint, so it is recommended to coat the car paint, and it is an inorganic coating.
The running-in period is to grind the mating clearance of the friction parts to a reasonable range within a period of time in order to achieve better lubrication. If the engine speed is too low during the running-in period, the impact of the crankshaft connecting rod bearing is greater, and the cylinder wall is easy to be strained if the speed is too high, causing early wear, so the running-in period should refer to the engine speed rather than the vehicle speed, the gasoline engine speed is between 2000 and 3000 rpm, and the diesel engine is between 1000 and 2000 rpm.
Does the current new car still need to be run-in? Regarding the run-in period of a new car, you may have heard a lot of such words: the accelerator and brake should be gentle, not too fast, do not go at high speed, and try to keep moving forward at a constant speed, otherwise it will hurt the vehicle engine and so on. >>>More
