The car was scratched, whether it hurt the bottom paint, what to do Thank you

In fact, the method of judging is very simple, generally we can use our fingernails to scratch the scratch and feel the depression. If the scratch can be stuck in the sliding of the nail, it means that the scratch is relatively deep, and the possibility of injuring the bottom paint is relatively large. If it's just a dimple that feels a little rough, it's not too much of a problem.

Generally, the surface of the car paint is scratched, and the primer is not damaged, just polish and wax.

However, according to the current car, if the paint surface of the vehicle is directly scratched, it will generally hurt the base paint and the car body, because the hardness of the paint surface is not scratched and there is a speed bonus. If the primer is really damaged, the metal inside the car body will be directly exposed to the air, and it will rust when it is wet. Of course, if only the paint layer is scratched, but the base paint is not damaged, there is no need to worry about rust.

Judgment method: Generally speaking, the primer and the car body will generally be injured in the direct scraping of the vehicle, usually in this case, the metal layer of the car body will be directly exposed to the air, coupled with the humid climate, it is easy to corrode the car body.

How to tell if you need touch-ups:

If the car paint is only scratched on the outside, it generally does not need to be treated immediately, because there is a layer of primer on the outside of the car to protect, and such scratches are not easy to find and do not affect the appearance. For many car owners who "dote" on the car, if you find that a small scratch can not judge the depth, you can touch it with your fingers, and generally you can't feel the scratches with obvious bumps and bumps, which means that the primer is not hurt, and you can ignore it temporarily, or deal with it later, but if you can obviously feel that there is a "line" to the touch, such scratches have hurt the base paint, and you should deal with it immediately.

Which scratches must be dealt with:

Of course, not every scratch on the car body must be dealt with immediately, generally speaking, if the bumper, rearview mirror and wheel arch and other engineering plastic parts of some cars are scratched, they will not rust, except for the ugly but no major problem. Whether to repair the paint or not depends on the requirements of the owner himself. But if these heavy scars appear on other parts of the body, then it is necessary to touch up the paint, otherwise even a small break, the steel plate will start to rust, and at that time, it will be difficult to prevent rust even if it is touch-up.

If the owner is not clear about which parts are plastic parts, he may wish to make a ** after the scratch occurs, and ask the 4S shop on the grounds of replacing accessories, so that he can clearly know which parts must be treated with scratches and which can be left alone for the time being.

Why should a scratch be sprayed on the entire part:

Many car owners don't understand when touching up paint: why do you have to paint the whole part with a small scratch? Depending on how long the vehicle has been used, the paint of the vehicle will more or less begin to fade, and it will produce a significant color difference if it completely relies on the color touch-up paint of the original car when it leaves the factory.

If you want to match the current color of the car as much as possible, you can only use the current tone. In order to avoid color differences as much as possible, even if it is only a small piece of the body that needs to be repainted, the maintenance personnel will repaint all the associated car bodies. This is for aesthetic reasons, and in daily use of cars, I believe that no one would want to go out in a car with obvious color difference.

Usually in the car repair shop or car 4S shop to touch up the paint, the technician will use the anti-rubbing strip as the boundary, and spray the upper half or the bottom half of the door. In this way, it is not easy to see if there is a slight color difference.

This one had to be touched-up. If the primer is exposed, there is no choice but to touch up the paint. It's not going to be ugly. There are some scum in society who can't look down on others as better than him,。。 This kind of person has nothing to do with a quilt.。。。

Dude, who told you to buy a BMW, if you buy a seahorse, no one will scratch it, and you haven't hurt the bottom paint Personally, I recommend not going to the 4S shop, find a bigger one, a better auto repair shop, and how long is your scratch?

There are three situations to remedy scratches in car paint:

1. Slight scratching of the body The damage of the paint surface of the slight scratch of the body is on the surface of the topcoat and can be completely repaired by waxing.

2. Injury to the body topcoat; If the scratches are a little deeper, part of the topcoat is scraped off, but the primer is not damaged and there is no serious deformation, and the paint can also be restored better by waxing.

3. Damage to the body primer and deformation. Injuries to the body primer and deformation through scratches on the body appear white, indicating that the scratch has damaged the primer. To repair this paint damage, we need to wear off the paint in the corresponding area, then perform a sheet metal repair and reapply the layers of paint.

Tips for body aging, scratch maintenance and repair:

1. Inspection and maintenance tips for the aging and scars of the body: no matter what kind of car there will be large or small scars. If it's a scar that isn't too noticeable, it's better to leave it alone.

2. Repair and maintenance tips for wear and tear scars: All cars have abrasions, and the best way to repair them is to fill the scars with the same coating agent as the body. The coating agent can be applied once, twice, and three times, and the more times it is used, the cleaner it will be applied. But even handling of the entire body is also important.

3. Repair and maintenance tips for small scarsIf you find scars in the body, check the extent of the scars first. If it is only a very light scratch of the surface paint, treat it immediately with a mixture, and wipe it in a straight line. Once the scar is gone, wipe it with a finer mixture before waxing.

4. Repair and maintenance tips for scratches and peeling paint: deep scars, the focus is to observe whether the metal surface is exposed, if you can't see the metal surface, it will not rust, and you can concentrate on applying the retouching paint. Use the tip of the pen to point it little by little, then wait for the paint to dry completely.

5. Tips for repairing and maintaining deep scars: deep but slender scars can be repaired well with colored putty. Use sandpaper to the scar, do not enlarge the scar surface casually, and it is important to remove the dirt. The putty should be carefully applied so that it completely enters the interior.

1. The scene of the accident.

1) When a traffic accident occurs, the owner must turn on the vehicle's hazard warning lights as soon as possible, and set up a hazard warning sign behind the car. The advantage of this is to prevent a rear-end collision with a vehicle behind you, so as to ensure the safety of the people in the car and the vehicle itself.

2) In addition to setting up warning signs, it is necessary to take pictures of the scene of the accident for evidence, which is the evidence of the accident to the insurance company, and the method of taking pictures before moving the vehicle is mainly to avoid the owner not recognizing the problem. Then fill in the corresponding accident rapid processing agreement, so that you can go to the damage assessment agency for vehicle damage assessment, so as to complete the corresponding maintenance and inspection work.

2. Stop immediately.

Stop the car as soon as it is safe to do so, turn off the engine (to avoid the car**) and turn on the emergency lights to make them shine; Immediately write down the license plate of the other person's car (pen and paper, or even a camera should be on hand at all times) in case the other person drives away after an accident.

3. Issue a warning.

Protect the site; Warning other vehicles and lighting hazard warning lights; Place triangular warning signs on the road; If necessary, use other methods to warn.

4. Nursing the wounded.

Never move the injured person unless they are in danger (e.g., fire, toxic leakage) as your movement may cause more damage. If the injured person is still breathing and bleeding is not much, no one else should do anything unless they really know how to care for the injured person. Do not give any food or drink to the injured person.

Automobile primer is the first coating directly applied to the surface of the surface of the self-treated parts.

The primer should have good adhesion to the substrate, have good matching properties with the middle coat or topcoat above, and have good corrosion resistance, rust resistance, oil resistance, chemical resistance and water resistance.

We can judge whether the primer of the car is worn by the following methods:

1. Generally speaking, the primer and body will generally be injured in the direct scratching of the vehicle.

2. Usually in this case, the metal layer of the car body will be directly exposed to the air, coupled with the humid climate, it is easy to rust the car body.

3. How to judge whether you need to touch up the paint: If the car paint is only scratched on the outside, it generally does not need to be dealt with immediately, because there is a layer of primer protection on the outside of the car body, and such scratches are not easy to find and do not affect the appearance.

4. For many car owners who are "doting" on the car, if they find small scratches, they can't judge the depth.

5. Then you can touch it with your fingers, and generally you can't feel the scratches with obvious bumps and bumps, which means that the primer is not damaged, and you can leave it alone for the time being, or deal with it later.

6. Finally, if you can clearly feel that there is a "line" to the touch, such a scratch has already hurt the bottom paint and should be dealt with immediately.

The car paint has been scratched by a treatment method: 1. Hair scratches can be easily removed with wax with fine-cut abrasives. 2. Minor scratches.

Repair with fine or medium-cut abrasive wax. 3. Moderate scratches. Open to the 4S shop and ask for touch-up paint or a touch-up paint pen of the same color number to repair.

4. Deep scratches. Go to the 4S shop for anti-rust primer treatment, and bake paint repair on the surface.

1. Hair scratches. Judging criteria: At high speeds, even the soot and sand in the air may cause subtle hair scratches on the surface of the paint. But I can't make a trace or a hand.

2. Minor scratches. Judging criteria: Leave a visible scar on the paint, but if you touch it carefully, the scar is very shallow, only slightly concave. In fact, this only hurts the transparent posture of the imperial calendar on the surface of the car paint.

3. Moderate scratches. Judging criteria: directly damage the color paint layer, you can clearly observe and touch the color paint layer. Of course, the best thing to do is to drive the car to the 4S shop and ask for touch-ups.

4. Deep scratches. Judging Criteria: If you find that the scratches on the car body directly expose the metal plate of the body, or the scratch area is more than the size of a fingernail, the wound is deep below the primer.

The way the car paint is scratched is treated like a rough stupid code:

1. Micro scratches: Daily use must not avoid being scratched by some hard objects to leave traces on the car paint, such as the zipper on the passerby's backpack or the small stones that burst when driving will leave slight traces on the car paint. Often, these slight scratches are the most common on the body, but they don't affect the aesthetics of the body, and I generally don't care about it in this case.

If you are a perfectionist and don't want to spend more money, you can try to use toothpaste to deal with it, apply it to some slight scratches on this reed, and then wipe it slowly to remove the scratches, because there are very fine particles in the toothpaste, and wiping slowly is equivalent to grinding off the obvious scratches;

2. Slight scratches: Slight damage to the rock is already very clear to see the scratches on the paint surface, in this case, it is recommended to use a paint brush to deal with it. Of course, you must buy a touch-up pen that matches the color of your car's paint.

One of the drawbacks of using a touch-up pen is that the place where it is applied will be very uneven, because after all, it is not covered by spraying, so after using the touch-up pen, the paint will be potholes after solidification, although it can't be seen fiercely, but you can still see it if you look closely. In addition, if the damage to your car paint is not very obvious or you don't want to use a touch-up pen, there is actually another way to solve it - stickers. It's also good to cover up scratches with your own favorite stickers, and it's better to look at it than with a touch-up pen;

3. Moderate scratches of the exposed primer: This situation shows that it must be rubbed with other hard objects, and it is not recommended to deal with the scratches of this exposed primer, because it is not only related to the appearance of the body, but also can make the body rust if it is not handled well.
