How to prevent rust on a Vauxhall Astra?

I have a Vauxhall Astra and I've noticed some rust starting to form on the body. How can I prevent this from getting worse?

Rust can be prevented by regularly washing and waxing your car to protect its paint and metal. Also, make sure to touch up any scratches or chips in the paint to prevent rust from forming.

You can also apply a rust inhibitor or rust converter spray to any areas with existing rust. Just be sure to follow the instructions carefully.

Another tip is to check and replace your car's weatherstripping and rubber seals if they are damaged. This can prevent water from seeping into the car and causing rust.
