About the method of car paint touch-up

About touch-up

First of all, in all places, even in the original factory, after the car is installed, the touch-up paint will not use any original paint! If the repair shop tells you that they use the original paint, it must be lying to you. The reason is simple: I mentioned above when I talked about the original painting process. After the paint is sprayed, it is baked at a temperature of 200 degrees. With so many parts on the finished car, how many can withstand a temperature of 200 degrees? Is it possible to take the car apart, leaving only the shell? Special touch-up paint is used for touch-up paint. The baking temperature of the refinish paint is relatively low, at 7 or 80 degrees.

Secondly, the color of the refinish paint is all formulated before the repair. The reason is also very simple: your car may have been driving for a few years, and the paint has begun to fade, although you can't tell. If you park outside, the degree of fading in different directions will be slightly different-the relationship between sunlight.

If you want to match the original color as much as possible, you can only adjust it now. Also, in order to avoid chromatic aberration as much as possible, even if you only need to touch up a small piece of paint, the factory will repaint the whole piece. For example, if there is a place on the car door that needs to be repaired, the upper half or the lower half of the fan should be fully sprayed with the anti-scratch strip as the boundary. In this way, if there is a small color difference, it is not easy to see.

Also, if you buy a car for beauty, you buy pearlescent paint. When you touch up the paint, be prepared to cry. It is difficult for the directionality of the lacquer mica particles to be the same as the original ones. Even if there is no color difference in the paint, the paint can be seen at a glance.

Now the computer color matching is under the premise that the operator is serious, the color difference between the paint and the original paint is indistinguishable by ordinary people's eyes. You can rest assured about this. The key is: the paint used, the equipment used and the sense of responsibility of the people.

There is no possibility to touch up the paint with the original paint. But under normal circumstances, the car factory will still recommend the designated refinish paint brand to the specialized repair station. A good repair station will also use a good brand. Such as ici, such as Nippon. However, in small shops, even some less formal specialized repair stations may use cheap paint for cost reduction considerations. At that time, the effect may be the same, and after 3 months, the color difference will come. This is almost impossible for our users to identify. Only look for a rest assured repair shop.

Although the baking temperature of the refinish paint is relatively low, it does not mean that it does not need to be baked or replaced by other methods. If you find that the repair shop does not have a special baking room, but uses a small sun to heat it. Change places as soon as possible! Unless you drive a bus.

Also, on the production line of a regular automobile factory, painting is done in a dust-free workshop. Although many purely domestic cars may not do this, it does not mean that it is unnecessary. If you see that the garage is very dirty and dusty. I suggest you change the place. Otherwise, even if it came out beautifully at the time, after a while, I have seen all the paint bubbling and peeling.

Retouching, apart from paying for paint, I am afraid we can only pay attention to so much.
