Red Seal Auto Body and Collision Technician Practice Exam

What purpose does body filler serve in auto body work?

1. To enhance aesthetic appeal

2. To fill dents and imperfections before painting

3. To reduce the weight of the vehicle

4. To protect against corrosion

The correct answer is: To fill dents and imperfections before painting

Body filler plays a vital role in the process of auto body repair, primarily serving to fill dents, scratches, and other imperfections on the surface of the vehicle. This compound is used to create a smooth, even surface that can be painted over, thus ensuring a high-quality finish when the vehicle is restored. The use of body filler is critical before painting because if the surface of the vehicle remains uneven or has visible imperfections, the final paint job will likely reveal these flaws, resulting in an unsatisfactory appearance. Body filler adheres well to metal and plastic surfaces, making it ideal for repairing a variety of damage types. While body filler can contribute to aesthetic appeal, its primary function is to prepare the surface for painting by addressing physical imperfections. Other options, such as reducing vehicle weight or protecting against corrosion, do not accurately reflect the main purpose of body fillers in the context of collision repair and painting processes.
