This is not necessarily true. Sheet metal is just an ordinary maintenance project, and all three types of maintenance enterprises can be competent. Therefore, most people who choose 4S stores are novices or people who don't understand cars. Because the maintenance cost of 4S stores may be more than twice as high as that of three types of enterprises.

If it is a high-end car, of course, it is to choose a 4S shop or a professional repair shop, because the paint of high-end cars is more complicated and the technical requirements are high. Although ordinary maintenance companies can also carry out construction, the effect will be much worse.

In fact, among all automobile paints, the original paint is always the best. Because it was high-temperature baking paint, the oven temperature reached 140 degrees, which lasted for 90 minutes. After the vehicle leaves the factory, due to the protection of most molecular equipment of the vehicle and the consideration of safety, the repaired paint surface is generally irradiated by far infrared, and the safe temperature is controlled between 45-48 degrees. Therefore, it is almost self-drying paint, and the hardness after coating will not exceed 4 hours.

Therefore, whether you need to go to the 4S shop depends on your own vehicle.
