Under what circumstances does the paint of a car need to be polished?

Polishing is a method of car paint care, when the car paint surface is oxidized or there are various foreign objects on the body, such as fine scratches on the paint surface, slight damage to the car paint surface and various stains, paint polishing is required.

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.

For this reason, in the process of waxing, glazing, coating and other car paint maintenance, it is inevitable to use the polishing process, but do not use too many times. In addition, the number of paint polishes on some Japanese models must not be controlled.

Experts remind that although polishing will make the paint thinner, it does not mean that the paint cannot be polished at all. Just note that it is better to have no more than 5 polishes in a car's "lifetime".

Extended information: 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.

When polishing, the polishing wheel rotating at high speed presses the workpiece, so that the abrasive produces rolling and micro-cutting on the surface of the workpiece, so as to obtain a bright machined surface, and the surface roughness can generally reach microns; When a non-grease matting polish is used, glossy surfaces can be matted to improve appearance.

When it comes to polishing, the most frequently asked questions are "what is polishing" and "does polishing hurt the paint". So today, the prince of car wash will come to give you a science popularization of what polishing is all about, and by the way, how to match the tools and materials used in it.

If the car body is not deformed and the metal surface is not exposed (the part that has not been repaired), we can remove the scratches on the paint surface by polishing

When the car paint surface is oxidized or there are various foreign objects on the car body, such as fine scratches on the paint surface, slight damage to the car paint surface and various marks, the paint polishing needs to be carried out.

Hello First, scratch treatment, second, paint oxidation, and third, paint blemishes can be polished.

New cars do not need to do polishing, in general, the polishing treatment is the vehicle paint aging, more scratches, and car dealers will do polishing when selling cars, in order to increase the brightness of the paint, the damage to the paint is certain, polishing is straightforward is grinding, the thickness of the paint itself is so thick, polishing once will reduce the overall thickness, so unless it is absolutely necessary, do not use polishing to treat the vehicle paint as much as possible.

Generally, it is not recommended to polish the new car, the new car polishing will make the paint thinner, if you want to do beauty for the car, such as waxing or sealing glaze, do not polish the whole car to remove the oxide layer on the surface of the paint. Moreover, the new car has a layer of original wax, polishing or waxing will destroy this layer of original wax, it is recommended that the body does not have any wax after half a year and then wax and plating will not cause unnecessary waste.

New cars do not need to be polished, and polishing is the damage to the paint surface of new cars. After one year of opening, you can consider polishing and plating.

If there are no scratches on the paint surface of the motor vehicle, it is best not to polish it, which will affect the gloss of the paint surface.

In fact, we divide paint repair into three processes, grinding, polishing and reduction.

Grinding and polishing, strong cutting ability, can be repaired for car paint.

Reduction can only act on the oxide layer, and cannot touch the car paint at all.

Therefore, for the decontamination and oxidation (de-blacking) of the surface of the new car paint, the reduction process can be used. Only the oxide layer is removed, and the paint is not damaged.

Do cars need to be polished after painting? Cars need to be polished after painting, and this is done to make the car more perfect. The reasons for this are as follows:

1. Spray paint engineers may accidentally let some impurities fall into the paint during the work process. 2. The dust in the paint room will enter the paint. 3. After spraying the paint, there are flaws in some places and need to be sandpapered.

4. Polishing can make the paint surface feel more flat. 5. There is no color difference between the interface between the new paint and the old paint. 6. It can make the paint surface smoother and brighter.

It should be noted that the car needs to be polished immediately after painting, and then it can be done once every few months, the paint surface is brighter, and frequent polishing is also a kind of damage to the paint protection film. @2019
