How to prevent rust on an Audi 80?

I recently purchased a 1991 Audi 80 and I want to make sure the body stays rust-free. What can I do to prevent rust from forming on my car's body?

Regularly wash and wax your Audi 80 to remove any dirt or debris that can trap moisture and cause rust.

Apply a rust inhibitor to any small chips or scratches on your car's body to prevent rust from forming.

Keep your car in a garage or covered parking area when not in use to protect it from the elements.
