What should I do if there are scratches on the paint? How to repair paint scratches

Minor damage: you can use a touch-up pen Most of the damage in this case is that you can see the scratches on the paint surface very clearly or the traces left by the friction of objects on the paint surface. Of course, you must buy a touch-up pen that matches the color of your car paint, but you don't have to worry about buying the wrong color, you just need to know what color to add to the official name of your car paint, and then buy a touch-up pen of the corresponding color.

However, 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 solidifying, although it can't be seen fiercely, but it can still be seen 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 than with a touch-up pen.

Moderate damage: go to a quick repair shop for repair If you encounter this kind of damage, it is estimated that your car is in close contact with the flower bed or the pillar on the ground, and the paint has clearly peeled off to reveal the primer (usually the primer is white). Generally, the paint is so bad that the primer must be treated as soon as possible to avoid the steel plate at the damaged place being corroded by rain or other objects.

Shallow scratches can be sanded with sandpaper to remove impurities and rust, and then the paint surface is restored, waxed, and finally polished with polishing agent until the paint film is smooth and bright.

If there are scratches on the paint surface, depending on the severity, if the slight scratches do not hurt the primer, you can generally go to the beauty shop to do waxing and polishing to solve it.

1.Use scratch repair wax, use a waxing sponge to grind the scratch and then apply glossy reducing wax or brightening wax; 2.Apply the toothpaste evenly to the rag and wipe the scratches; 3.Rub off rust spots with sandpaper dipped in water and paint with a touch-up pen.

Observe the lacquer surface and polish it.

What should I do if there are scratches on the paint surface, I can find a beautician for professional treatment, just like new.

(1) Paint pen repair method. Applying a paint pen of a similar color to the scratch is a paint pen repair method. (2) Spraying method.

Scratches are repaired using traditional touch-up paint methods. The disadvantage is that the damage area of the original paint is too large, the repair time is too large, and the effect is difficult to be satisfactory.

1. Basic methods of car scratch repair.

1) Lacquer pen repair method.

Applying a paint pen of a similar color to the scratch is a paint pen repair method.

This method is simple, but the adhesion of the repair paint is not enough, and it is easy to peel off and difficult to last.

(2) Spraying method. Scratches are repaired using traditional touch-up paint methods. The disadvantage is that the damage area of the original paint is too large, the repair time is too large, and the effect is difficult to be satisfactory.

3) Computer paint mixing spraying method. Combined with the deep scratch repair technology of computer paint mixing and new process methods, this is a fast technical repair, but it requires accurate color matching, the repair area is reduced as much as possible, and then after special solvent treatment, the new and old topcoats can be better integrated to achieve optimal adhesion.

2. If the mirror treatment of automobile topcoat is polished with sandpaper and "coarse wax", it is difficult to make the car paint achieve the mirror effect. Therefore, automotive paint care materials must be used in the treatment of automotive paint mirrors. At present, putty and polishing agent are generally used, and the best material for mirror effect is polishing agent.

In fact, polishing is also an abrasive, which is an abrasive that contains a friction material with finer particles. The size of the material particles or efficacy of the polish is divided into three types: micro polishing, medium polishing and deep polishing. Micro-polishing is used to remove very slight paint damage, generally refers to the environmental pollution and acid erosion (guano, fallen leaves, etc.) that have just occurred (within a few days), but this kind of minor damage can currently be replaced by wax containing polishing agent; Medium and deep casting are mainly used to deal with different degrees of hair scratches.

In addition, the effect of medium polishing is better for transparent paint, while deep polishing is faster for ordinary paint.

Generally speaking, polishes and reducing agents are the same class of materials in terms of the friction materials they contain, but the main difference between the two is that the reducing agent contains a polishing material (polish or wax), while a polishing agent does not contain a polishing material. It is important to have a "mirror effect" on automotive paints with non-glazing materials.

The main ways to improve the gloss of automobile paint to achieve the "mirror effect" and polish are:

1) By grinding and rubbing the material, the fine scratches are hard to remove.

2) Relying on the efficacy of wax, after polishing to a certain extent, rely on the luster of wax to make up for the defects of polishing.

3) Relying on chemical reaction, that is, relying on the adjustment of the speed of the polishing machine to produce the chemical reaction of the polishing agent.

The first two methods are more used by beginners.

The main reason is that beginners do not have enough understanding of the speed of the polishing machine, the material of the polishing head (wool material, blended material, sponge material and cotton material, etc.), the structure of the lacquer and the relationship between the efficacy of the polishing agent, and lack of experience, so the requirements for polishing are not high.

What should I do if there are scratches in the car paint? The treatment method of car paint scratches is as follows: 1. Slight abrasions:

I didn't see the metal of the body, that is, the varnish layer was basically destroyed, it will not affect the life of the paint, but it is not beautiful when you look closely, so there is no need to touch up the paint, you can use toothpaste to wipe on the scratches, with the help of fine particles in the toothpaste, fill the gaps in the paint scratches and grind them off. Or sand it with coarse wax and the scratches will slowly disappear. 2. The scratches are relatively large and long

The scratches on the paint surface have traces left by friction, and the color of the scratches is different from the color of the paint, which is a mild scratch damage, which is difficult to repair with toothpaste, and it is difficult to repair the color of the scratches. For minor scratch damage, the most important thing is to make up the color of the paint, which has a greater impact on the appearance. 3. If you buy a car with a small can of original paint, you can evenly apply the original paint to the primer, and be careful when applying.

If you don't have the original paint, you can buy a paint pen and use the paint pen to treat the paint. Be sure to shake it carefully before using the touch-up pen, and brush it repeatedly when touch-up, with an interval of 5-10 minutes between each brush. When it is completely dry, carefully sand it with sandpaper.
