Red Seal Auto Body and Collision Technician Practice Exam

What should be done if a vehicle shows signs of rust damage?

1. Ignore it, as it will not progress

2. Sand it down and apply a rust-inhibitor

3. Spray paint over it

4. Cover it with a clear coat

The correct answer is: Sand it down and apply a rust-inhibitor

Choosing to sand down rust damage and apply a rust-inhibitor is the most effective response to address the problem. Rust can significantly compromise a vehicle's integrity and aesthetic appeal if left unattended. By sanding down the area, you remove the rust and any affected paint, allowing for a clean surface that can be effectively treated. Once the rust is removed, applying a rust-inhibitor helps to protect the metal from future corrosion by creating a barrier that prevents moisture and air from coming into contact with the surface. This not only helps in stopping current rust damage but also works to prevent new rust from forming. Other options, such as spraying paint over rust or covering it with a clear coat, only serve to mask the issue without addressing the underlying problem. Ignoring rust entirely will lead to further progression, resulting in more significant damage that could require more extensive repairs down the line. Therefore, addressing rust with proper treatment is crucial for maintaining a vehicle's longevity and safety.
