How to prevent rusting on my Audi A2's bodywork?

I have noticed some small spots of rust on my Audi A2's bodywork and I'm worried it will spread if I don't take action. What can I do to prevent further rusting?

First and foremost, regularly washing your Audi A2 will help prevent rusting as it removes any harmful substances like salt and dirt that can cause corrosion. Make sure to also wash the underbody of your car as that is where rust can easily start.

Applying a protective wax or sealant to your Audi A2's bodywork can also help prevent rusting. This creates a barrier between the metal and any moisture or pollutants.
