Cars, what to do before polishing? What is the detailed process of car polishing?

1. First of all, clean the whole vehicle with a paint cleaning agent with strong detergency to avoid new scratches caused by particle dust in the grinding;

2. Secondly, for the coating surface with coarse grains, fine sandpaper marks, flow marks and other defects, before polishing, use 600 to 1000 water sandpaper dipped in water and wrap it in a small rubber liner, and gently polish it to a flat surface, pay attention not to wear through the paint layer; Then use a mechanical grinder and coarse abrasive paste to coarse grind the traces of water sandpaper, and add abrasive paste to polish and grind; The mechanical polishing machine is used, and the mirror treatment agent is used to throw away the marks left by the coarse abrasive paste to achieve the effect of mirror polishing of the paint film;

3. After grinding and polishing, wipe the 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.

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.

1.The principle of polishing.

It is smoothing, so polishing is damage repair. Therefore, the paint surface should not be polished too much, once or twice a year is enough.

2.Polished foundations.

The paint surface is composed of three layers: primer, intermediate coating and varnish, and if the scratch is only in the varnish layer and does not damage the intermediate coating, it can be polished.

3.Polishing is only a remedy for the lacquer finish.

The best way to protect the paint surface is waxing, sealing glaze and coating polish are mainly divided into light polish and dark polish, as the name suggests, it is dark polish for dark cars, and light polishes for light cars. Another function of polish is to act as a strong cleaning agent or "stain remover" before waxing. After "washing the face" of the car, it is necessary to apply a layer of reducing agent, also called "sealant", which is used to restore the original appearance of the car paint.

What is the process of car polishing?

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. Hope the above is helpful to you, thanks.

If the car's paint needs to be polished, the paint is bad. There are a lot of flaws. If the car has been driven for a long time, the paint will be yellow.

There are many scratches on the paint surface and need to be treated. There is gray paint on the lacquer surface. In these cases, polishing is required, and the car is polished.

After throwing the light, it is best to do a maintenance of the paint surface, such as waxing and sealing glaze coating and gold plating, and these projects can be done. It can better protect the car paint.

Polishing refers to grinding the original color of the paint with equipment after scraping the surface of the paint.

The question of whether the car should be polished should also be looked at specifically, not that polishing will definitely cause damage to the vehicle paint, on the contrary, there are benefits. So under what kind of circumstances is the most suitable for polishing, I will share it with you below.

First of all, we have to figure out what the role of car polishing is, car polishing can also be divided into active polishing and passive polishing, the main purpose of active polishing is to increase the brightness of the paint surface, so as to achieve their own satisfactory results. Passive polishing is a process that forces us to do a paint maintenance process for the vehicle under some irresistible factors.

How to maintain your car:

1. The cushion and backrest should be cleaned.

The cushion backrest in the car is prone to bacterial growth, so it should be removed frequently for cleaning and disinfection. Exposure to the sun ensures cleanliness and reduces bacterial infections.

2. Check the brake failure.

Under normal circumstances, the brakes do not fail. But to be sure, it's important to check brake failures frequently.

3. Keep the glass clean.

The mirror in front of the car must be kept clean and wiped every day. If it is dirty, it is easy to block the view when encountering a dusty road.

When you buy a car and drive for a certain period of time, some external factors such as pollution and environmental pollution are affected. The surface of the paint is eroded to a certain extent, and different oxide fading will appear on the surface of the paint Divided into: early, middle, late, and broken copper and iron.

It is only the appearance of the damage, because it does not require large-scale maintenance in the early stage, because it is left alone for a long time, it has a great impact on the car paint. Slowly it will corrode to the varnish layer! Therefore, polishing is generally for some cars whose paint surface has been dull, has dirt and oxide layer that is difficult to clean, or has scratches in the car paint.

Because these scratches or deep dirt can't be removed by cleaning.

Hello, the role of polishing;

1. Treat minor damage to automobile paint.

2.Removes minor oxides and impurities from the surface of the paint layer.

3.Eliminates subtle scratches caused by abrasion.

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

1.Preparation materials: polishing machine (can be replaced by an electric hand drill), hand drill suction cups, sponge suction cups, corrugated sponge suction cups, fiber suction cups, wool suction cups, scratch wax, liquid wax or solid wax (depending on the paint selection).

2.Car washing: clean the appearance of the vehicle, if there are stains or scratches that cannot be washed off, you need to combine the electric hand drill with the corrugated sponge suction cup, and then squeeze the scratch wax on the corrugated sponge, and polish the stains and scratches that are difficult to remove on the car paint.

In the process of operation, just throw away the scratches and stains, and do not always aim at one place to grind, otherwise there will be the phenomenon of burning.

3.Wax sealing: When the scratches and stains are removed, you can seal the wax, replace the previous corrugated sponge with a flat sponge, and then squeeze the solid wax on the sponge and evenly apply it to the body.

Pay attention to the strength of your hands during the application process, and wait for 15 minutes for the wax to dry thoroughly on the body. It is recommended to use solid wax because it is harder, it will last longer, and the effect and gloss after splashing water are better than liquid wax.

4.Wax throwing: touch the wax on the body with your hands, and if there is wax powder on your hands, it proves that the wax has dried thoroughly and can be used for wax throwing. The previous flat sponge was replaced with a fiber suction cup, and the wax powder on the surface of the body was discarded, leaving only the wax that had adhered to the paint surface and solidified thoroughly.

5.Polishing: Replace the previous fiber suction cup with a wool suction cup, and smooth the uneven surface wax, you need to pay attention to the polishing strength in the process, too light to throw the surface of the wax out of the mirror effect, too heavy and will throw away all the wax.

The above 5 steps are the whole process of polishing and waxing.

Car polishing steps: 1. Use car wash liquid to clean the surface of the car paint, especially hard things like dust particles, otherwise it is easy to wear out the car paint in the process of grinding; 2. Select the corresponding water sandpaper and dip it in water, and roughly polish the surface of the car paint until the scratches are smooth; 3. Select an appropriate grinding machine and add polishing wax to polish and grind the polished place; 4. Wipe the part that has been thrown through the light with a mirror treatment agent. Car polishing is the process of car beauty, in the waxing, glazing or coating of the car first to do a polish.

Because the sealing glaze coating must be polished first, and it is a finely polished car to make a mirror, this is the operation that the sealing glaze must go through.

1.First of all, clean the whole vehicle with a paint cleaning agent with strong detergency to avoid new scratches caused by particle dust in the grinding;

Secondly, for defects such as coarse grains, fine sandpaper marks, and flow marks on the coating surface, wrap 600 to 1000 water sandpaper in water in a small rubber liner before polishing, and gently polish it until it is smooth, paying attention not to wear through the paint layer; Then use a mechanical grinder and coarse abrasive paste to coarse grind the traces of water sandpaper, and add abrasive paste to polish and grind; The mechanical polishing machine is used, and the mirror treatment agent is used to throw away the marks left by the coarse abrasive paste to achieve the effect of mirror polishing of the paint film;

After grinding and polishing, wipe off the grinding and polishing paste and immediately dip it in cotton yarn.

Car polishing is a kind of polishing the car before the car is waxed or coated, because the vehicle only looks like a sparkling effect after the vehicle is polished, and the effect of the car that has not been polished is generally not long-lasting after waxing. The main working process is to clean the body first, and remove the dust of those particles in the cleaning process to avoid secondary scratches to the vehicle, polish after cleaning, polish after grinding, and wax after polishing to see the car look new, but is it often polished, is it not as long as the car is dirty can be polished.

Remove car surface stains and remove scratches: When there are scratches on your car and you are distressed, or there are some stains that cannot be cleaned, you can choose car polishing, after the car polishing has been reduced by mirror, you can clean the body paint to the previous state, and at the same time, you can also throw away some oxides and corrosives attached to the body such as acid rain and bird droppings, etc., and after polishing, the car paint is also a certain protective effect.

Thin car paint, poor self-maintenance ability: in fact, car polishing is like a person removing the cuticle, once or twice is good, when the number of times, you will find that the ** is getting thinner and thinner, and even can not withstand a little damage, the same is true for car paint, car paint is not regenerated, after layers of throwing, it will only become thinner and thinner, and even lead to the phenomenon of car paint throwing through, and too many times of polishing will also lead to the original self-maintenance ability of the car paint to deteriorate, the hardness will also deteriorate, it can withstand a small pebble, Now it can only withstand a small grain of sand.

Hello, first of all, make sure the paint surface is clean!
