How to repair the paint off the car has a lot to do with the condition of the car and the damaged location. If the paint of an old car that has been used for many years is damaged and the paint of a new car is lost, the repair method chosen by the owner is definitely different. The former is that old drivers are used to scratching car paint, so it is likely to use a touch-up pen to make up for it themselves, or find a roadside shop to touch up the paint.

But novices are different, depending on the car as life! If the car is painted, you must go to a professional repair shop to repair it. After the process treatment of professional baking room and "three sprays and three baking", problems such as color difference are avoided!

According to the different degrees of scratches on the car paint, we can appropriately choose different repair methods to restore the body at the lowest cost. Then we can divide it into three degrees, slight scratches on the body, damage to the body topcoat and damage to the body primer and even deformation.

First, the body is slightly scratched:

If it is only a slight scratch on the body, that is, the scratch only hurts the most superficial layer and is not deep, this can actually be repaired by waxing.

Second, hurt the body paint:

If the scratch is deep, and part of the topcoat has been hung up, but there is no damage to the primer and deformation, then we can repair the paint by ourselves to restore the paint surface, the easier and faster is to buy a touch-up pen, and then follow the tutorial to touch up the paint. Here's a tutorial on how to fix scratches with a touch-up pen**.

3. Injury to body primer or even deformation:

If this is the case, then the scratch is already very serious and will develop into rust later if not treated in time. To repair the undercoat and deformation, the paint is sanded off, the sheet metal is repaired, and the coats of paint are reapplied. The repair cost in this case is relatively high, if it is low, it is the one mentioned before, a few hundred dollars, if the repair area is large, and the quality of the paint is high, then it can be as high as thousands of yuan.

1. After the paint is scratched, the first place to scratch is whether it is in the front bar and rear bar of the car or some other position. 2. Generally, the front and rear bumpers and fuel tank caps of automobiles are plastic, and the paint surface is relatively thin. If you scratch and don't want to repair it, you can buy a paint pen to deal with it.

3. If the injury is in other parts of the vehicle, such as the door panel, etc., at this time, it is necessary to look at the car paint.

If the car is painted, you can buy the kind of touch-up pen on the Internet and make up for it yourself. If the paint falls off more severely, it is recommended to send it to the car repair shop to repair it, because it is a more professional place to repair the paint.

1. Damage the body primer or even deformation.

2. The body is slightly scratched.

3. Damage to the body topcoat.

Quite corresponding 3 fixes:

1. Damage the body primer or even deformation.

If the body is not white, observe the color of the scratches on the body, if the color of the scratches is inconsistent with the color of the body paint, it means that the scratches have damaged the primer. To repair this paint damage, it is necessary to wear off the paint in the corresponding area, then carry out sheet metal repair, and finally respray the layers of paint. This fee is relatively high, mainly based on the degree of realization, the face of the sheet metal, the specific model and the quality of the paint.

The low one is about 200 yuan, and the high one may be as high as tens of thousands of yuan.

2. The body is slightly scratched.

Slightly scratched paint damage is mostly on the surface of the topcoat, not very deep, this can be completely repaired by waxing, and will not leave a bad paint surface. The cost of waxing is not very expensive, and if you have a good relationship with the master of the repair shop and it is not a serious injury, he may also treat you for free.

3. Damage to the body topcoat.

If the scratches are deep, or even part of the topcoat is scraped off, but the primer is not damaged and there is no serious deformation, the paint can also be restored better by waxing.

How can I tell if the primer has been damaged? If the body is not white, observe the color of the scratches on the body, if the color of the scratches is the same as the color of the paint on the body, it means that the primer is not damaged; If the body is white, since the primer is generally white, it is necessary to judge whether the primer is scratched and checked by a professional painter.
