Anyone know of a good tool or a way to get paint into those hidden areas where you just want some covering but not worried about appearance? I was thinking of some type of flexible hose with a spray tip that shoots radially .

What??? No... seriously. Dip the sponge in the paint and shove it wherever you need... ... you know...
Thanks Anthony. I had ordered the same thing from a different ad on Amazon just a little before your post. When I clicked on your post, I saw it was an almost identical ad to what I bought......BUT, then I saw another one from the same company that had 2 hoses and a metal cup for just a little more. Figured that was a better choice than having to buy the small plastic bottles for $8 ea (Eastwood on Amazon). I assume that there are cans of different stuff that screw on as well. Anyway, I think I will like the one with the aluminum cup even better. So I attempted to cancel my order and reorder this one. Would not have seen that if you hadn't helped. You must be used to dealing with some larger crevices than me Actually that might work pretty well for sloshing inside a door, but right now I'm concerned with protecting some kinda small openings underneath a new steel body with nothing to protect it from the elements. Maybe some smaller brushes or some gun cleaning rags to swab in there.
What I use is a 60 year old pump up garden sprayer with an adjustable pattern nozzle on a long wand. Great for doing inside frame rails or other hidden areas. Probably not too pretty but it covers well and is never seen anyhow.
I have a few of those I bought a while back, but they won't get inside like I want. Here are some pictures.
Seriously, if I had similar type parts that were NOT attached to the car, I really would be tempted to pour paint into the cavities and turn the part over and over to coat it somewhat evenly. Would be messy and wasteful, but effective.
I'd been having similar deliberations on the same body (Bville 3w coupe) and I decided that as long as everything is well covered in cavity wax there shouldn't be a problem. Im not using any seam sealer either as I figured I'd want any moisture ingress to have as many exit points as possible. Also, the car will spend the majority of its life in a garage which should keep it well as long as its not damp. I've used various waxes previously but have gravitated to Dinitrol (can't recall the product code). Its initially like piss so I'm thinking it will wick into all the places it needs to go. This viscosity will give rise to quite a bit of waste but in the context of a $25k bare body its irrelevant. Once applied it dries to a thin, waxy film. For the avoidance of any doubt im talking about stuff intended for cavities which are not exposed directly to weather or abrasion where a stone chip (which might also have chemical rust preventative properties, as a Dinitrol product has) would be more appropriate. I've had my coupe body on a rotisserie that I built (so I could work at a comfortable height and orientation) and have just finished painting it. I deliberated on whether to apply Dinitrol whilst still on the rotisserie but decided against it for fear of contaminating things and making any paint reworks difficult (I'm assuming Dinitrol is laced with silicone). I'm not too concerned whether my overall strategy will hold good though as as long as it lasts about 15 or so years it'll probably outlast me and will be the next guys problem, probably a grandson!

Here are some pictures and explanation of what seems to work pretty well for getting paint into those hard to reach places. Won't be any show quality, just gettin paint into and onto those inner panels that will immediately begin to rust if not coated with something. Even inside a boxed frame. My pictures above show some of the places I was trying to get some paint on. I ended up using an undercoating gun with a flexible hose and a nozzle in the end of the hose. At first a lot of sputtering or nothing. Tried thining the paint which makes it run into crevices more easily.....and also out of the crevices and onto flat panels. Be prepared to wipe the run off up with some cheap lacquer thinner........but paint does get into a lot of unreachable places. I had to drill the nozzle holes larger even though I thinned the paint. I found that holes in the nozzle of appx .110 diameter seemed to work well with a viscosity cup time of about 17 seconds. So if you try this, those two things should get you flowing.........
