How to prevent rust on the Vauxhall Insignia's body?

I have noticed some rust forming on my Vauxhall Insignia's body and I'm not sure what steps to take to prevent it from getting worse. Can someone provide some advice on this issue?

Regularly wash your car, especially during winter when salt can cause corrosion. Make sure to also clean the underside of your car as it's more prone to rust.

You can also apply a rust inhibitor or wax to the affected areas to help slow down the rusting process.

Another tip is to keep your car in a garage or under a shelter to protect it from harsh weather conditions.

If the rust has already formed, you can use a sandpaper to remove it and then repaint the affected areas.
