How to prevent rust on your Audi A6?

I noticed that my Audi A6 has started to develop rust in some areas. How can I prevent this and keep my car looking in top condition?

Perform regular inspections and clean your car regularly, paying special attention to the undercarriage and wheel wells. You can also apply a rust inhibitor spray to any areas that are prone to rust, and consider getting your car rust-proofed professionally. Additionally, avoid driving in harsh weather conditions and make sure to fix any scratches or dents on your car's exterior as soon as possible.
