1970 Chevrolet C20 Pickup - Removing and Prevent Rust in Motor Area

[ggalv]

Hi,

There is some rust in some of the metal parts in the motor area. Trying to find out what is the best way to deal with this. Is there something that I can use to remove the rust? Or is removing the rust something more involved and requires someone with more experience with this kind of stuff?

Is there something that I can use to maybe prevent the rust from getting worse? Not sure if I should use WD-40? Spray or apply it with a towel? Or if there something else that is recommended?

Also, I have some jump starters that have rust. I am assuming they are metal, not sure if they have some cooper. How should I go about removing the rust from these

Appreciate your help, thanks.
