In the daily use of the car, it is inevitable to encounter a lot of bumps and bumps, and it is inevitable that it will cause some scratches. It is natural to touch up the paint after scratches, but why do you have to touch up the entire door after only a little paint has been dropped? Actually, the reason is very simple.

1.Avoid color aberrations.

If it is a smooth paint surface, if it is a partial recoat, the brightness is poor, the color is poor, and even the possibility of an embarrassing interface between the old and new paint surfaces is very high! Due to the problems of the spraying process, the mixing process and the quality of the paint, it is almost impossible to avoid color differences. Even if the paint is the same color, the degree of newness of the paint will look different, which will create a sharp contrast.

At the same time, if only local scratch points are treated, then its interface can not be well handled, because the paint area is small, and the surrounding paint surface and the paint surface of the new paint cannot be transferred naturally, so the size of the paint area is clear at a glance. So once there is a color difference, the paint surface looks like a big patch, which is very ugly. Therefore, in order to ensure the quality of maintenance, as long as it is painted, 4S shops or repair shops usually spray paint in a large area.

Shop the problem of the profit of the repair shop.

If it is only because of scratches that cause a little paint on the door, for the 4S shop repair shop, the process and time required to repair a little paint and complete the door paint are about the same. The same step requires painting and baking, the same amount of time taken in the paint booth and the gun needs to be cleaned.

However, the entire painting process is a very time-consuming job. A person can't spray several cars a day, which may also be limited by the number of spraying booths. Maybe everyone is waiting to use the paint booth, and the time spent in the paint booth is the same, which makes the repair shop need to raise the price as much as possible to make money per unit of time.

If only a little paint is added, the 4S shop repair shop may lose money on this project.

Of course, not all places in the car are available, as there is one area that needs to be thoroughly painted. There are actually two places where you don't have to do this, and that is the front and rear bumpers. Because both of these places are plastic and have a large area, even if you spray a small piece of paint, the color difference will not be so obvious.

The reason why the bumper and door area are different is that the door is made of iron, and the bumper is made of plastic, and the paint attached to the plastic is different from iron.
