Body panels are the exterior parts of a vehicle that form its structure and shape. These panels include components like the hood, doors, fenders, and trunk lid. They are typically made from materials such as steel, aluminum, or plastic, and are designed to protect the internal components of the vehicle while also contributing to its overall aesthetic. In addition to providing protection, body panels play a crucial role in aerodynamics and fuel efficiency. They are often designed to minimize air resistance, which can improve a vehicle's performance. Proper alignment and fit of body panels are essential for safety and functionality, ensuring that everything works together seamlessly.
