I've used both Ospho and POR15 with good results, I probably overdo it, but I like to get it as clean as I can before using the coatings. The Ospho converts the iron oxide to iron phosphate, which is relatively stable, at least that's what I've been told. Before I got an air compressor, I've used a wood handle wire brush, a vacuum cleaner (to suck up the crap with), and lots of elbow grease, then the ospho (rubber cloves, safety glasses, and a rag and carefully swab it on so I'm not leaving puddles of it around....)let it dry, brush off the white residue (there's always some it seems), and even wipe it down with clean water and a rag if it seems sticky in places, let it dry thoroughly, then the primer and finish coat of your choice. Rustoleum has always worked well for me.
I like the POR15, but if you need to rework the area later, man that stuff is miserable to get off, and you need to get it off if you are going to do any welding or other heat work. I did some '55 stock rims with it once and they came out quite nice, and still look good 10 years later. I did topcoat them with a gloss black to prevent the UV effects. Our local paint store sells it, I buy the smallest cans, it costs more that way, but then I don't have leftovers turning hard almost immediately and having to throw it away....
The trunk in my '55 hardtop is worse then you pix and I will be doing it with Ospho, after welding up a couple of holes.....
