Which tool is commonly used for metal straightening during collision repair?

The hammer and dolly method is widely recognized as a primary technique for metal straightening in collision repair. This approach involves using a flat or shaped metal tool, known as a dolly, placed behind the damaged area while a hammer is used on the front side to reshape the metal back to its original form. The combination of these two tools allows for precise control and manipulation of metal surfaces, making it effective for addressing dents and warps resulting from collisions.

Using a hammer and dolly, a technician can gradually massage the metal back into alignment without causing further damage to the panel. This method is particularly advantageous because it can be applied to a variety of shapes and sizes of damage, making it a versatile choice in collision repair.

Other tools mentioned, such as a sledgehammer, are typically not suitable for precise metal work due to their weight and size, which could lead to larger dents or make it difficult to control the impact. Pneumatic wrenches and torque wrenches, while useful in other areas of auto repair, are designed for fastening and loosening bolts and do not play a role in the metal straightening process. Thus, the hammer and dolly are the preferred tools for technicians when it comes to restoring the shape of damaged metal
