Which method is used to repair minor tears or damage in sheet metal?

The hammer-and-dolly technique is well-suited for repairing minor tears or damage in sheet metal because it allows for precise control over the metal's shape and surface finish. This method involves using a hammer to gently shape and manipulate the metal, while the dolly acts as a backing support to absorb the blows and help restore the metal to its original contour. The primary advantage of this technique is its ability to carefully work the metal without creating additional damage, making it ideal for small repairs where maintaining the integrity and appearance of the sheet metal is essential.

This technique is especially useful for addressing dents, creases, and minor tears as it encourages the metal to return to its original form without requiring excessive force, which could lead to further deformation. Additionally, it allows for effective blending of the damaged area with surrounding undamaged areas, thus achieving a smooth finish.
