The cases where car dents cannot be handled by paintless dent repair mainly include permanent metal deformation with over-tension damage to the car paint, damage to key structural parts, severe coating damage, or large-area dents. Specifically, dents in key parts such as the edges of the car body sheet metal or the frame are not suitable for paintless repair due to their complex structure and safety implications-forced repair may lead to greater deformation; areas that have been repainted are prone to paint cracking under external force, making paintless repair also inapplicable. Plastic parts cannot be restored to their original shape due to their material properties, and dents on door edges may compromise sealing performance. If the car paint has cracked or the dent area is excessively large, traditional methods like panel beating and repainting are typically required. Notably, acute or obtuse angle dents with intact factory paint, hail dents without paint damage, etc., remain suitable for paintless dent repair, but the specific solution should be determined after professional technicians assess the extent and location of the damage.
