Halfway through rustproofing

Having spent inordinate time researching how to rustproof the inside of a fully boxed frame, I decided to do a more temporary job of just spraying it with oil. So far I've sprayed the inside with warm degreaser, followed by a thorough rinse, now it's drying. I thought the inside of the frame would just be dirty, but it's actually as rusty as the outside. Should I head straight to spraying oil like I set out to do, or is it going to come back to haunt me if I don't clean up the rust somehow? It's hard to get in there; will just spraying inside with phosphoric acid do the job?

The inside looks like this outside:

you can use a spray wand to get in there and use wax, por 15, or a rust encapsulator. Can also use a phosphoric acid to pretreat it but it may cause adhesion problems if you don't neutralize it fully or get it out. It looks like very minor surface rust. Nothing to worry about. Using por 15 as directed would do the job and then some.

acid wont work very well now that theres oil on it.Matter of fact,you wont get ANYTHING to stick until all oil is gone. I would get all the oil off and sand blast the frame then with a big wire wheel cupand Ospho I get out the remaining rust out but dont try neautralizing it, its a myth, just let it dry .the steel will be protected until your ready to spray the primer which should be an epoxy for the best results and protection...
OR just do it like you are and oil it but dont try painting or priming it'll just peel off...

There's no oil yet. I was all set to spray it when I thought I might get rid of the rust first.

Again, I'm talking about the *inside* of the frame, not the outside. POR15 won't work as, in my experience, it requires a very thorough prep job, which is impossible to do inside.

I'll be sanding and painting epoxy primer for the *outside*. The first photo shows my first attempt at sandblasting parts of the frame. Works great, but no way to do that for the inside.

I would sand blast the out side. Paint the out side then spray the inside will oil.

That does sound like the way to go...
I cant believe nobody has invented some kind of sand blasting wand or something made just for this,its a common enough question that I've never heard a good solution for.
Electrolytic would probably be the best DIY way to do it if it was all apart but you would have to build a tank big enough to submerse the frame.I knew a guy that did his truck cab this way and it worked very ,very well,the hard part was building the tank (plywood and a swimming pool liner) after that you just connect the power source and walk away for a couple days..
I tried it on a smaller scale and it was very ez to do even my for my first time,I was very impressed how well it worked,no rust at all...
