What is the most effective way to prevent rust on my Audi 80's body?

I've noticed some small patches of rust forming on my Audi 80's body and I want to prevent it from spreading. What are some effective methods for preventing rust from forming and spreading on my car?

Make sure you keep your Audi 80 clean and dry. Excess moisture can lead to rust formation. Regularly wash and dry your car to prevent any buildup of dirt or debris that can cause rust.

Consider applying a rust inhibitor or sealant to your Audi 80's body. This will create a barrier between the metal and moisture, preventing rust from forming.
