How to prevent rust on my Ford Transit Custom?

I just bought a Ford Transit Custom and I want to make sure that it doesn't get affected by rust. What are some preventive measures I can take to keep my car rust-free?

Regularly wash and wax your car to protect it from salt, dirt and other corrosive substances that can lead to rust.

Apply an anti-rust coating or sealant to your car to protect it from moisture and corrosion.

Keep your car in a garage or covered parking area to protect it from rain and other harsh weather conditions.
