Final answer:
Technician A is correct; paintless dent repair does require special tools and equipment. Technician B is incorrect; this technique is not used for repairing structural damage but rather for minor dents and dings.
Step-by-step explanation:
Technician A is correct in saying that paintless dent repair requires special tools and equipment. This technique involves the use of specialized tools to push or pull dents from the inside of a panel without disturbing the paint. Therefore, specific training and tools are essential to perform this task effectively.
On the other hand, Technician B is not correct. Paintless dent repair is typically used to fix minor dings and dents in the metal panels of a vehicle and is not suitable for repairing structural damage. Structural repairs generally require more traditional bodywork, including reshaping or replacing damaged parts and possibly repainting.
