Collision Repair Practice Exam

Paintless Dent Repair (PDR) is a widely used technique for repairing dents without the need for paint. This method focuses on manipulating the metal back to its original shape using specialized tools. PDR is effective for minor dents and dings, particularly those that haven’t damaged the paint layer.

The process involves accessing the back of the panel to gradually push out the dent, which minimizes the risk of further damaging the surface and preserves the original finish of the paint. This is particularly advantageous because it often results in faster repairs and can maintain the vehicle's value by avoiding the need for repainting.

Other methods may not focus specifically on non-paint procedures or address different types of damages. For instance, traditional hammer techniques may involve more extensive hammering and sometimes lead to paint damage, while dry ice treatment is a less common and less reliable method that works on specific types of dents. Scratch fill techniques are intended for repairing surface scratches rather than dents, making them unrelated to the question about dent repair specifically.
