I’m so glad my nickname is Helen as in Keller, and Stevie as in Wonder.

I never bend down to look under my truck. @Oldfart may be gaining on me.

Rustoleum Pro enamel. Flat black. For all of your "I need it to be black instead of rust" instances.

So update Ford surprisingly is replacing the complete reared Assy with new and giving a premium extended warranty. Completely blown away.

It's their halo truck in the F150 lineup. It's literally the most important vehicle for Ford image-wise.

If you point out how rusty their halo is, they will at times do something about it.

Rust-Oleum Rust Converter spray in black is AWSEOME for this kind of thing. I did my truck within a few days of taking delivery and it still looks good. My '20 had a lot less rusty spots than yours though. I scuffed lightly with sandpaper and sprayed it. The diff and the yoke were the worst spots on mine.

When I first got my truck 2 years ago I knew to expect some rusty crap underneath. I went to a really good local hardware store actually looking for the brush on rust converter and the owner turned me onto this spray. I had never seen it before either. I spent less than an hour doing some sanding, wiped everything down, pulled the stupid labels off the axle, and taped off some spots (like the driveshaft) and sprayed it. It looked awesome. It says to wait 24 hours to topcoat. I only top coated (satin black) the diff and the axle, but everything stayed really nice long term.
