My rust, how do I operate?
I found some rust while ripping the car apart for various cleaning/painting and I'm not sure what I should do.
The pictures attached show 3 angles of the same spot to give the scope of the issue. The rust in the pictures is (appears) mostly surface rust but where you see the blue arrow there is a spot which is kind of bad. I am sanding down the area and repainting but I'm not sure if this area is gonna make it. This area is the bottom of where the front bumper shock mounts. The picture which has 2 red circles is where the battery would normally just about cover. Does any of this front section actually unbolt off or am I gonna be looking for someone to cut/weld things back?
Incidentally, the first 7 people that suggests I use Mariah as spare parts for another 7 get kicked in the *****!

If it is mainly just surface rust, I would sand it down well, and paint it with some por-15. It is designed to keep rust from spreading and in my experience has done a good job. http://www.por15.com/
I agree - get the heavy rust scale off with a rotory (ha!) wire brush, then get the POR metal ready to prep the surface, then apply the POR15. Its better than just paint because it will bind with the rust a form a near-bullet-proof finish. These are all frame-welded components so its not like you can unbolt these and swap them easily - unless your a genius with a welder? try to knock down the rust first with the POR. I have used it to touch up all sort s of rust points on my SA with great results...

Since that area is a block, 4 sides of metal, how should I go about getting inside of it to make sure there is no rust in there? Can't can I? Is there some sort of spray I can shoot in there that eats rust, after which I can coat the block(outside)?

POR-15 is amazing... I totally rebuilt a rear end with it...
And the strut housing / front suspension parts... avoid all threads... it hardens rock hard.
The way POR-15 works is it bonds with the rust and sucks the moisture out of it... this is what hardens it up and why anything near it never rusts again. If it happens to chip (stuff is rock hard, takes some real effort to chip it), only the little chip will rust, nothing around it.

I guess whereever I can get to the rust, I will grind it down and POR15 it. Wherever I suspect there is internal rust, I will see if I can get into there at least enough to poor the POR15 into the hole and hope it seeps in there and bonds.

You can brush or spray POR-15. But keep in mind that contains isocyanates so you really need fresh air mask if you are spraying. I've only brushed it since I do don't have the safety equipment to spray.
And believe the instructions when they say not to get it on your skin. If POR-15 dries on your skin nothing but time or a grinder will remove it. If you are going to paint the underside of the car, your best bet is a disposable fabric jumpsuit and old cloths underneath. Keep your hair protected and wear gloves. I didn't take this advice and ended up with approximately 40% of my body sealed in POR-15 for almost 2 months.
