Bottom paint

I'm planning on painting the underside of the floor pan, the bottom of the bed, and the frame rails on my '77 F250 Supercab. Other than overspray from the body color, did the factory paint the bottom of these vehicles any particular color? Mine seems to have a faint hint of silver on the cab bottom, and frame rails have some possible black paint. No undercoating is present anywhere I can see, except maybe inside the fender wells. I'm kinda thinking of rust bullet, with maybe some body color over that.

The black on the frame is called 'chasis black', kind of a thinned black paint. The gray is a anti-rust coating. Rust Bullet is a great product to use for undercoating.
