Nondestructive repair is limited to dents with undamaged paint. If the paint is broken, it can only be painted with sheet metal. If there are only minor scratches and dents, it is recommended to repair the dents.
Traceless repair of automobile dents is also called paint-free repair of automobile dents, which is used to repair various pits, dents and depressions on the body surface caused by the outside world. This technology uses a special series of tools and restorers to restore the dent of the car body to its original state conveniently and quickly without destroying the original car paint, and uses the visual effect of light refraction to judge the position and degree of the dent, and uses the lever principle to massage the "skin" inside the car body and gradually release the tension on the surface of the dent of the car body. After repair, the sunken part will never be deformed or faded, and the sunken part of the car body can be repaired quickly, accurately and thoroughly, instead of general repair. It has the characteristics of fast repair time, original paint maintenance and reasonable cost.
If the dent in the door is not serious and the paint is not damaged, you can try to repair it yourself. You can buy a set of car dent repair tools online, and the tools are basically complete. But be careful when repairing, or the depression may become prominent. It is still difficult to repair the depression. If the sag is small, the effect is not obvious. Unless the depression area is large and gentle, it is easier to operate and the effect is obvious. Of course, if you don't want to do it, you can also go to the repair shop to repair the dent.
There are still great limitations in the seamless repair of car body depressions. For example, the depression is deep and still on the body line, so it is more difficult to repair the depression and the effect is not obvious. If there are cracks, paint is still needed.
