Is that paint or a coating or real rust?

I forget the name of the specific steel (my brain is mush at the moment) but the rust actually seals the surface of the steel stopping the oxygen from getting to the metal. Thus it stops rusting. We used this stuff on a lot of bridges. However it would stain the concrete and that was rather ugly. If I remember they stopped using it because in areas where water washed over the steel it washed off the oxidation (aka rust) and allowed degradation of the structure. It would be cool to make body panels of that steel. It was also a darker brown rust. Almost chocolate brown with a hint of red.

Ok I remember now it is called "weathering Steel"

Probably more than you want to know about the stuff http://www.steelbridges.org/pdfs/Weathering.pdf

I wanted to make running boards and bumpers for my old 78 c20 with the stuff.

Sounds like the stuff my dad's F-150 frame is made of. It's rusty, but it stopped getting rustier 15 years ago. Too bad they didn't make the rest of the truck out of that.
