Rust Proofing Products?

[Rocco P.]

Wondering which products our DIY rustproofers are using to protect their trucks. Also, are you just spraying the under carriage? What about aluminum body areas?

subscribing as i am wondering the same thing.

I'm leaning towards spraying the $hit out of the undercarriage, and then just lightly spray the body through holes that already exist. I am doing Krown undercoating oil spray

I will use my hose as needed. No undercoating.
