1, the technology is not mature enough: the seamless repair technology can not completely guarantee that the appearance of the repaired car is consistent with the original state, and there may be some slight differences.
2. Permanent deformation: If the concave part of the car body is stretched excessively, the metal car body may be permanently deformed, and the car paint may also exceed its deformation tension, resulting in local cracking of the car paint.
3. Safety hazards: Traceless repair may affect the structure and safety of the vehicle, and the repaired parts may have weaknesses, which cannot guarantee the same strength and stability as the original body and increase safety hazards.
