What is the best way to prevent rust on the Volkswagen Touareg?

I've noticed some rust starting to form on my Touareg and I want to prevent it from spreading. What steps can I take to protect my car?

Regularly wash and wax your car to create a barrier against moisture and prevent rust.

Use rust prevention sprays or coatings on any areas that are prone to rust, such as the underbody.

Address any scratches or chips in the paint immediately to prevent rust from forming.
