When restoring a dent in metal, why might a technician avoid drilling?

When restoring a dent in metal, a technician might avoid drilling primarily to maintain panel integrity. Drilling can weaken the metal structure of the panel, leading to further complications such as reduced strength and resilience. Maintaining the integrity of the panel is crucial, especially in areas where structural support is needed. Additionally, drilling creates unnecessary holes that could be hard to repair and may lead to rust or corrosion over time if not sealed properly.

Preserving the original shape and durability of the panel is essential in auto body repair, as it helps maintain the visual aesthetics and functional performance of the vehicle. Avoiding drilling allows technicians to use other repair methods, such as pushing or pulling the dent out using specialized tools, which provide a less invasive approach and protect the overall condition of the panel.
