What to do if there are polishing marks after the car is polished, and how to remove the traces left

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.

If it is a new car, it is okay to regularly wax the car by hand, but if there are some small scratches on the surface of the paint and the wax cannot be disposed of, you can choose car polishing. Generally, if the whole car is polished, it will take at least half a day, the whole car should be washed first, and then polished with 3m polishing fine sand, and then the coarse wax will be thrown, followed by fine wax and beauty wax, handmade wax, and finally the car will be washed. Generally, the whole car is polished once 300 500, which depends on the local economic situation.

Polishing and waxing is a kind of protection for car paint, and of course it is beneficial.

If you have a problem with the polishing angle, adjust the angle and then throw. The angle is reasonable, even if there is a print, the whole car is one color. So the point is that there is something wrong with your polishing angle. Try changing the angle a bit to make the force and speed a little more even.

Hand waxing is sufficient.

Car polishing can remove scratches. For the oxidation, dullness and dullness of the car paint, and the scratches on the body, the car polishing can be effectively processed to make the paint surface smoother and brighter. In addition, car polishing can also clean the car body, effectively remove dirt and corrosion, and achieve the purpose of restoring the cleanliness of the paint surface.

Polishing the body before waxing and glazing can make the result better and keep it longer.

Apply wax to protect repaired spots. Apply a high-quality wax to the surface and polish the surface with a random polishing pad.

Let's do it again, you can't draw circles when waxing.

Also, the sun pattern is almost impossible to remove, if you don't want to be troublesome, make a glaze, and then wax once every 15 days, I don't know what kind of car you are, I can't recommend the right wax for you, hehe.

Can you still leave traces after throwing it away? Isn't it contradictory. Do you want to polish it?

In a situation like yours, it's good to go directly to someone and leave it behind, or you can just push the wax to get better.

If you don't know anything about buying a new car, you will inevitably have some stumbles, which will cause some scratches. What makes many car buyers distressed is Chunyou, this kind of scratch endangers the beauty of the new car, so how to eliminate the scratch.

Actually, scratches can be thrown off by polishing. Polishing according to the high-speed operation of the polishing wheel, can grind off the air oxide layer and stains on the surface of the car paint, and can efficiently remove micro scratches. So, can a new car be polished with scratches?

If a new car has scratches, it stands to reason that it can be polished, as long as it is a slight scratch, a little polishing is also OK, and the car paint may be able to bear it. However, it is proposed that polishing and waxing is good, and the application of sand wax is unique, and the unique abrasive particles of sand wax can also be abrasive to remove scratches, and relatively speaking, polishing and waxing is likely to be less harmful than polishing to the new car, and the implementation is more reassuring.

If the scratch is deep and hurts the topcoat or metal material layer, it is necessary to repair the paint first, wait for the paint to be completely hard bottomed, and then carry out careful polishing to solve the problem. Generally speaking, the new car paint is cost-effective, not easy to air oxidation, and the flat posture often pays special attention to maintenance, and there is no need to polish at all. For the old car, the proposed condition, 3-5 years of car book paint gradually embrittlement, at this time polishing can make the paint finally glossy.
