How can I prevent my Nissan Qashqai from rusting?

I've noticed some rust starting to form on my Nissan Qashqai and I'm worried it will spread. What can I do to prevent it from getting worse?

Regularly wash your car and keep it clean to prevent dirt and debris from accumulating. This buildup can trap moisture and accelerate rusting.

Apply a rust protection treatment or wax to your car's exterior to create a barrier against moisture and other elements that can cause rust.

Regularly inspect and touch up any chips or scratches on the paint of your car. These can expose the metal and make it more susceptible to rust.
