How to fix rust on an Audi A3?

I've noticed some rust on the body of my Audi A3. How can I fix it and prevent it from spreading? Any specific products or techniques that would work best?

Hi Samantha. Rust on cars is a common problem, especially in older models like the Audi A3. To fix it, the first step is to sand down the rusted area until you reach bare metal. Then apply a rust converter solution and let it dry. Finally, use touch-up paint to cover the area and blend it with the rest of the body. As for preventing further rust, make sure to wash your car regularly to remove any dirt or debris that could cause rust. Also, consider using a rust inhibitor spray on the undercarriage and vulnerable areas.
