What is the best way to prevent rust on an Audi 80?

I recently purchased an Audi 80 and I'm concerned about potential rust issues. What steps can I take to prevent rust and keep my car in top condition?

Regularly wash and wax your car to protect the paint. This can also help to remove any dirt or salt that may lead to rust formation.

Keep an eye out for any scratches or chips in the paint and have them repaired as soon as possible to prevent rust from starting in those areas.

Apply a rust inhibitor to any areas that are prone to rust, such as the bottom of the doors or the undercarriage.
