If there are slight scratches in the car paint, there are generally two ways to repair the car paint: touch-up paint pen and car wax.

If you feel that the paint brush is a little rough, you can also use repair wax, that is, car paint repair wax, which may require a certain amount of hands-on ability, the step is to use reduction wax first, polish the scratched part of the car paint, study it, and then use repair wax, basically you can achieve a state of the original car!

Disadvantages of car waxing:

1. Easy to oxidize

Car wax is based on petroleum as a solvent, so it will oxidize, forming an "oxidative resonance" with the car paint. Generally speaking, the wax begins to oxidize in half a month and is completely oxidized after a month. After the oxidation of the car wax, it cannot protect the car paint for a long time.

2. Easy to wear paint surface

Generally, wax contains abrasive particles, and the brightness of the paint is actually made by grinding the particles that cannot be seen by the naked eye. If the waxing technique is always polished in circles, then the car that is often waxed will have a thin outline in circles.

3. It is not resistant to high temperatures

Due to the dual effects of sunlight and engine operation, the temperature of the paint surface is very high. In summer, the surface temperature of the hood can be close to the "boiling point", even in winter it can reach more than 30 degrees, and at such high temperatures, the wax is very easy to melt and lose, and the melted wax will adhere to more dirt and further damage the paint surface. The car glaze will also accelerate oxidation under the action of high temperature.

4. It is not resistant to cleaning

Wax is soluble in water, so if the car has just finished waxing and encounters rainy weather, the wax will be dissolved by the rain, and it will not play a role in protecting the paint and beauty. At the same time, because the wax is soluble in water, washing the car after waxing also causes a lot of inconvenience.

1. Touch-up paint pen, you can buy it according to your own body color, and use the touch-up paint pen to repair the scratches in the scratches, which is quite convenient. And the paint repair pen is not expensive, dozens of pieces, and it is still possible to repair scratches.

The treatment method for minor scratches on the car is as follows

1. Clean the scratches on the car with clean water and dry them, wet the towel slightly, apply toothpaste to the towel, and wipe the scratches vigorously.

2. As long as you wipe it slightly, the shallow scratches and some scratch residues will be wiped away immediately.

3. This method deals with the remaining paint of the other party when scratching with other vehicles, the effect is immediate, most of them can be wiped clean, and this method is suitable for cars with very shallow scratches.

4. Body wax, this method is relatively simple, and the effect is also very good, apply body wax to the place of small scratches, soak the towel with warm water, and wipe the wax applied to the scratches several times with a towel, and the small scratches can be removed, so that the treatment will also improve the brightness of the paint surface.

Paint scratches are divided into hair scratches, shallow scratches, medium deep scratches, and deep scratches, and the best methods for repairing them are polishing, toothpaste, filling putty touch-up, and sheet metal treatment.

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 traces left by the other party's car paint when scratching with other vehicles, or 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 requires a relatively high technician technology, and the advanced technology of CHINAP can make your car quickly restore its original appearance in the shortest possible time.

2.According to the size and depth of the scratch, select the appropriate polishing material to polish the scratch surface. Generally, it is polished by manual operation, and it can also be polished with a grinder.

Care should be taken not to grind through the topcoat layer during the polishing process. If the topcoat layer is worn and the intermediate paint layer is exposed, the topcoat must be sprayed to remedy it.

3.The polished lacquer finish has largely eliminated shallow scratches. For some hair scratches and rotary prints left during the sanding operation, the reducing agent can be evenly applied to the paint surface with a small piece of non-woven fabric, and then sanded until the topcoat is exactly the same color as the original coating;

4.Wax the paint surface after restoration. First, the solid polishing wax is mashed and put in gasoline to dissolve hot. Wet the repaired area with clean cotton yarn first, dip it in wax and wipe it again. Wipe repeatedly until the paint film is smooth and shiny. When waxing, the whole vehicle can also be waxed and polished;

5.After the above procedures are completed, check the appearance quality. The focus of the inspection is that the color of the coating must be exactly the same as the color of the original paint film. If there are discrepancies, the surface cleaning and waxing and polishing do not fully meet the requirements, and rework if necessary.
