How to prevent rust on a Vauxhall Corsa?

I have noticed some rust on my Vauxhall Corsa and I am worried it will spread. What can I do to prevent rust from forming on my car?

Regularly wash and wax your car to prevent dirt and moisture from building up and causing rust.

Check for and repair any scratches or chips in the paint as soon as possible.

Apply a rust inhibitor or protective coating to vulnerable areas of your car, such as the bottom of the doors and wheel wells.

Keep your car in a covered or sheltered area, especially if you live in an area with harsh weather conditions.
