A good reflection board or PDR (Paintless Dent Repair) light is crucial for achieving precise and flawless results in dent repair. These tools help provide clear, detailed visual cues by illuminating the surface of the vehicle, allowing technicians to spot and assess the dent's shape, depth, and contour. A well-lit, high-quality reflection board or light enhances accuracy during the repair process, ensuring the technician can work efficiently and restore the vehicle's surface to its original form without damaging the paint. Proper lighting is key for achieving a seamless, professional finish.
