Now I'm tasked with, how do I treat the insides of my doors so they don't rust any more than already probably are? Spray rust neutralizer in there and hope for the best? I also have a jug of metal etch.....is that a good solution?
If I can get satisfactory results from one of those or something ejlse, what's a good way to coat the inside to protect from future? Spray it with primer and paint and hope for best once again? I'd also like to deaden the panels so what about sound deadening spray? Keep in mind I don't have much access and I don't want to cut the door open.
This is on a 1960 door.

I expect you may get better answers but here's what I've done (and if I see a better answer I'll change my approach)
.
I clean the door as best as I can - and then hose it out outside and blow it out with air, and tilt it so you get all the water out. Once dry, I lay it flat on one of those folding stands, inside up and tape up the obvious holes, like door locks, from the outside. Then I pour some rust encapsulator inside and tilt the door around until it's completely covered inside. Often you can see it seeping thru the edge of the door skin. Then I tilt the door up and pour the excess out a drain hole. Once well drained, I lay it back down, do my best to wipe off any leaks and drips, and leave it until it dries. Seems to work great for me. I have a quart of Eastwood Rust Encapsulator waiting for my doors.
