The car has been scratched and the primer is exposed. Can I still use a touch-up pen to repair it?

If you want to prevent the raw embroidery and surrounding paint from peeling off, you can do it.

If you want to be perfect, then you are thinking too much.

Many paint touch-up pens claim that they are original paint and that they are convenient, trouble-free and can cure your obsessive-compulsive disorder. However, they are all just teasing you.

There is no original paint at all, but the car manufacturer will provide the 4S shop with touch-up paint. You go to the 4S shop to do the whole car painting, which is the touch-up paint used. These touch-up paint are usually expensive. And more 4S stores have their own paint mixers. This position is a bit scarce. Because with the huge increase in domestic car ownership, the salary of paint mixers is increasing day by day. Small 4S stores simply cannot afford to hire paint mixers. , you have to buy paint from a large store. The advantage of the paint mixer is that you can save money on buying the original paint. The disadvantage is that when you go to the 4S shop and ask for the whole car to be painted, the master will take a look at it and then according to his own requirements. If you use experience to mix colors, there will definitely be errors with your original colors.

If you can even see that the paint on your car, which was mixed by an experienced paint mixer, has color differences, you can just buy a touch-up pen and it will perfectly match your car. The colors are exactly the same! It's simply a fool's errand. Even if it happens occasionally, it's just that it's infinitely close. This is considered lucky.

Suppose you are really lucky. The color you bought is the same as the paint color of your car. So of course it is impossible to repair the exposed bottom. You have to understand why the original factory The paint is always better than the entire car sprayed by your 4S shop. You also have to understand why some luxury cars cost more than ten or two hundred thousand to repaint because the process is complicated.

There are four and five layers of car paint. I don’t know much about the five-layer paint. The four-layer paint is probably the most common. First, after the car parts are made, they are thrown into the paint and rinsed. As for whether the paint is colored or not, I don’t know. This layer is called the electrophoresis layer. As the name suggests, the entire part is completely soaked in the paint, so even the smallest corners can be soaked, and 4S stores obviously can’t do that. At this point, your entire car will be painted without this layer of electrophoresis layer. If even a 4S shop can't do it, wouldn't it be amazing if a small touch-up pen could do it?

The electrophoretic layer provides anti-corrosion and improves the adhesion of the mid-coat. The role of the mid-coat is equivalent to what we often call putty, smoothing the entire surface and preparing for the coloring layer. Make the coloring layer plump and smooth after spraying on it. The touch-up pen should remember this function. I guess you have to manually putty and polish it before applying color. But once it is polished, will it damage the surrounding paint surface for some flaws? Anyway, I wouldn't try it if I was handicapped.

After the mid-coat is applied, there is the coloring layer, which is the color of our car paint, and then the varnish layer, just like girls applying nail polish. If you want it to look good, you must first Apply a layer of nutrient oil to protect the nails and use a color conducive to the color, then apply color, and then apply a layer of bright nail polish. First, the color will be glossy, and second, the color will last long without oxidation or fading. A varnish coat works the same as polish.

The paint on your car is just like this, layer by layer, and if you want to touch up the effect of the original paint with just one layer of touch-up pen, I'm afraid that it will make you suffer from obsessive-compulsive disorder.

In my car, there was a small hole in the door. It was very small, about the size of a grain of rice. I don’t know how it was made, but it exposed the bottom. I drove to the 4S shop, took a branch and put some paint on it. Last point, get it done, if it’s broken, it’s broken. The more you mess with it, the bigger the injury will be. Cars are driven by people, so you don’t have to mess with them just because of small scratches. If you drive them for a few years and there are more scratches, you won’t care anymore. It won’t hurt much. , do whatever you want, and when you sell the car after driving it for a few years, you take it to a 4S shop and spray the entire car, and it still sells for a good price.
