If the vehicle is scratched, does it have to be repainted?

After scratching, the car generally needs to be repainted, but it also depends on the degree and area of scratching. Generally, small scratches do not need to be deliberately removed.

No. Because the cost of repainting is too high, just touch up the paint directly, so it is not necessary to repaint.

If the car is scratched, it is recommended to choose to repaint, otherwise the appearance of the car will be more ugly.

To be polished. Otherwise, the unevenness is unsightly, which will also affect the effect of the new paint, there is color difference, it is easy to fall off, and light spots appear. If the 4S shop is painted and used normally, the car paint can basically be maintained for 4-5 years, and the original paint of the 4S shop should be polished off.

There are several reasons why the original paint should be polished before painting:

1. Re-spraying paint will increase the thickness of the paint film. If the original paint is not disposed of, the spray paint will be placed higher than the surface of the original paint.

2. If you don't dispose of the original paint, after the new paint and the old paint are fused, they will separate and fall off, and they will be sprayed in vain.

3. If you don't treat the original paint, even if you just spray the new paint, the effect is very good, and when you come back to wash the car, the water gun is flushed, and it is very easy to fall off.

4. If the original paint is not treated, there will be color difference.

5. Two different colors or qualities, especially a reaction that occurs when mixed together, makes the previous paint layer and the paint layer sprayed again not overlap, so that the paint surface appears light spots.

A lot of times it's like this, and the car has a little paint off it, or there is a scratch that is not too long, but it hurts the primer. If you don't touch up the paint, you always feel ugly, if you touch up the paint, the whole piece of the place where the paint is off has to be repaired, and it is not cheap. For example, if the paint is on the door, then the entire door should be repainted, and on the fenders, then the entire fender should be repainted.

Why can't you only repair the paint and only repair it, and only make up a little place?

The reason is very simple, there are two purposes for this, the most important reason is to avoid color difference, ensure the quality of maintenance, and secondly, to ensure the profit of the maintenance plant. Let's talk about the color difference first, as long as there is a slight difference in color on the same object and the same plane, it can be clearly seen. Because of the spraying process, paint mixing technology and the quality of the paint, it is impossible to achieve no color difference.

Then the degree of newness of the paint can also be clearly seen, the freshly sprayed paint is very new and bright, and the surrounding paint is relatively old, which can also form a sharp contrast. The second is that the interface cannot be handled well, because the painting area is small, and the surrounding paint surface and the newly sprayed paint surface cannot be naturally transitioned, resulting in the size of the paint area can be seen at a glance. Once there is a color difference, the paint surface is like a patch, which is very ugly.

Therefore, in order to ensure the quality of maintenance, as long as the painting is sprayed, it is sprayed in a large area. If we take insurance, when the insurance company compensates us, it will also pay for the entire surface of the painting, not just the cost of spraying the injured part.

The second reason is the profit problem of the repair shop. Assuming that the injured part is on the door and only a little paint has been lost, the time it takes to repair the paint is about the same as that of the entire door. The painting process is the same, and no step is missing.

The same step of paint mixing, after spraying and baking, occupies the same time in the paint baking room, and the spray gun also needs to be cleaned. The difference in time is the time spent sanding and the time spent during the painting process, both of which are very small. The time is about the same, and then the painting is much worse, the ordinary car sprays the entire door of the ** to four or five hundred yuan, if only a little place on the door, the asking price of one hundred yuan is already quite high, which is four or five times different.

Painting is a more time-consuming type of work, a person can not spray a few cars a day, which may also be limited by the number of paint rooms, everyone may be waiting to use the paint room, so the higher the unit time to make money, if most of them are to make up a little paint of the vehicle, then the 4S shop is going to lose money in painting.

Yes, depending on your scraping area, if the area is smaller, you can not spray the whole vehicle, you can choose partial, or semi-spraying.

However, this is more difficult for paint factories or 4S shops, because the spray part is more obvious than the original color, so that customers are easier to see the color difference, so the general 4S is to do the work of the whole vehicle door to prevent serious color difference and reduce complaints.

However, there are also excellent painters who control the color more accurately, and the subsequent painters transition the color is better, and the color difference is basically invisible.

There is an option to repaint the repair. It is recommended to go to a regular 4S shop for painting repair for the following reasons:

1.From the moment the vehicle enters to the time it leaves, there is a strict pick-up process. After the quality mutual inspection between each process and the general inspection of the quality inspector and confirm the signature with the customer before delivery. For objections after repair, the 4S shop will follow up and solve them to the end.

2. Sheet metal and spray Weipei lacquer technicians must pass the manufacturer's professional and technical training and certification before taking up their posts, and they can only take up their posts after they are qualified, and each maintenance has a very strict standard operating specification process.

3. Be familiar with the structure of the vehicle and have high maintenance quality. The vehicle needs to use a lot of special tools, which is a task for 4S shops. The treatment before painting is more detailed, and 100% spraying primer protection is applied before spraying color topcoat.

Expand the guessing information:

There are two kinds of touch-up paint, one is partial painting and the other is painting the whole part.

The body only has a slight scratch "leakage primer", which is generally used to repair the local paint technique, and the original scratch parts and the surrounding area are treated for local repair, the benefits of this are very obvious, convenient and fast, save money and materials, and the disadvantage is that the color difference is large (more obvious in the sun) and even the paint surface is uneven after repair.

The painting of the whole part is much stronger than the effect of local touch-up painting, of course, the finger width is **, and the time cost is relatively high. For example, the front bar adopts "whole spray", and the paint surface of the entire front bar needs to be wiped off with sandpaper, that is, the color paint layer is removed to expose the middle coating, and then the entire front bar is painted, which reduces the color difference of the whole part.

Summary. Hello, this is generally a spray of noodles. That is, the side you scratched, you don't need to spray the whole car.

The car is only scratched a little bit, does it need to be repainted in its entirety?

Hello, this is generally a spray of noodles. That is, the side you scratched, you don't need to spray the whole car.

What kind of car are you?

I drove the battery car and scraped a little paint under the BMW door, and the owner spent 16,000 on all the spray paints, so this is a bit of a pitfall, generally the following side, a few thousand yuan can be. How can the whole car be sprayed?

Yes, because I was driving in the wrong direction at that time, and the BMW came out of a Tang and ran into it, the owner thought that I was responsible.

The main cost of self-paid maintenance is not very reasonable. Did you call the police?

I reported it, and asked me to pay 16,000, I was angry and ignored it, 19 years ago, and now the insurance company sent me a lawyer's letter, alas, I feel uncomfortable.

This ** is indeed unreasonable, general maintenance. It's all about hurting one side and making a face, such as a little bit of a door. Just make the whole door, master, I thought the BMW car had to be sprayed all.

I've also been in a BMW 4S shop, and I don't have you like that. It's conventional.

It's all a little wounded, and if you make a face, there will be a lot of injuries, such as five or six noodles, and then you will spray them all.

Master, I just don't understand, I thought I was going to spray it all, and now people are too unqualified.

This one is really a bit of a bully,

The ways to solve scratches on car paint are:

1.clean the scratched parts of the car;

2.Soak the sandpaper with water, wrap it in a hard cotton cloth, and then polish the scratches with the wrapped sandpaper;

3.Use prepared tape and rags to plug up areas that don't need polish;

4.Shake the touch-up bottle up and down to touch up the paint.

Automobile paint coating is to coat a layer of film on the car paint surface, the purpose is to protect the gloss of the car paint surface from fading, and at the same time get a layer of protective film on the paint surface, so as to achieve the purpose of protecting the paint surface. Polymers, simply put, are molecules linked together hand in hand, and due to their strong film-forming, they can form a real film.

1. Hair scratches. Hair scratches can be removed by polishing or applying abrasives, and they can be wiped lightly. 2. Shallow scratches.

For superficial scratches, you only need to prepare a tube of toothpaste, which has a very obvious effect on superficial scratches that do not hurt the car primer. In particular, most of the paint left by the other car when scratching with other vehicles, or the traces left by some sticky products such as stickers, can be wiped clean. However, it is important to note here that you should not use toothpaste with small particles and abrasive ingredients, otherwise it will only backfire.

3. Medium-depth scratches. Medium and deep scratches cannot be repaired by grinding methods, and the concavity of a small area is not more than 5mm, which can be leveled by filling putty and then touch-up paint. If the metal is exposed at the scratch, it is necessary to clean the surface coating rust and welding slag, polish it flat, then apply an oxidation neutralizer with anti-rust effect, spray the primer, and repeat the painting, drying, and grinding to repair.

4. Deep scratches. If the deformation is more serious, it will be treated with sheet metal. The treatment of scratches has relatively high requirements for the technician's technology, and the advanced technology of CHINAP can make the car quickly restore its original appearance in the shortest possible time.

Reminder: If the car surface is affected by external forces and the primer is damaged, and the scratches on the car cannot be treated in time, nail polish can be applied first to prevent oxidation and rust on the damaged area. And generally small body scratches also depend on where it is, if it is in the bumper, rearview mirror and other places, because these places are mainly engineering plastics, will not rust, the owner does not have to be nervous.

However, applying nail polish is only an expedient measure, and only for small scratches, for general scratches or large scratches, the owner needs to go to the store as soon as possible to repair it.

The paint is scraped, just go to the 4S shop to repaint.

If you have insurance, you will report insurance, and if someone else scratches you, call the police.
