I stripped my hood on the top side with a 40 grit sticky back sand paper on a DA. It left a nice spiral/swirl etching on metal that made a great base for the primer. Two wet coats of primer, and not a sanding mark is visible.
The trick here is the spiral pattern of the DA which is gentle enough not to gouge the metal, but the 40 grit is aggressive enough to cut through the paint and rust.
You can do the same of the bottom side for the flat areas, and then use a wire cup for the bracing and other difficult areas.
Here is what the sanding pattern looked like before the primer.
