What's the best way to protect my Volkswagen Passat from rust?

I've noticed some rust starting to form on the bottom of my Passat. How can I prevent it from spreading and protect my car's body?

The best way to protect your Passat from rust is to regularly wash and wax your car, paying extra attention to the undercarriage. This will create a protective barrier against moisture and salt, which are the main causes of rust.

Another trick is to use a rust inhibitor spray on any areas that have started to rust. This will slow down the spread of rust and give you more time to properly address the issue.

Don't ignore small rust spots - they can quickly spread and cause serious damage to your car. It's important to address them as soon as possible.
