I've used Zero-Rust for frame painting, but am wondering how it would work for painting the inside of a pickup bed and touching up minor rust spots on the body before finish painting.

Will the rust protection be diminished by sanding before topcoating?

How does Zero-Rust do going over top of previous finish paint? I didn't know if it would only work going over rusted metal. Areas such as the bed will have some remaining finish paint.

Thanks for the help.

Can you still call it a barn find if it's your barn?
