How to prevent Rust on my Ford Focus' body?

I recently noticed some rust forming on my Ford Focus and I'm concerned about the long-term effects it can have on my car's body. What can I do to prevent further rusting and maintain the appearance of my car?

One way to prevent rust on your Ford Focus is to regularly wash your car, especially in winter when salt and other chemicals are used on roads. Also, make sure to dry your car thoroughly after washing to prevent any remaining moisture from causing rust.

Applying a coat of wax to your car's exterior can also help prevent rust by creating a barrier between the metal and any moisture or chemicals.

If you notice any chips or scratches on your car's paint, make sure to touch them up as soon as possible to prevent rust from forming. You can find touch-up paint at your local auto store.
