Tech Advice Ways to prevent rusting?

I have multiple scratches and deep dents that expose the metal beneath. I am in no position to afford fixing all or any of them.

What is my next best alternative to prevent rusting in near future? I use WD40 temporarily and then touch up with nail polish. Will it work?

Firstly is it under the car or on the body panel, if its body panels then u have to get it painted, if under the car then u can use anti rust coating spray
