How can I protect my Nissan Qashqai from rust?

I have noticed some rust spots on my Nissan Qashqai and I'm worried it might spread. What steps can I take to prevent it from getting worse?

Regularly wash your car and make sure to remove any salt or debris stuck to the undercarriage. You can also use a rust prevention spray on exposed metal surfaces.

Have your car inspected by a professional to determine the source of the rust and get it fixed immediately. Also, consider getting an undercoating treatment to protect the underside of your car.
