Default Lang 84 restoration

I've picked up a Lang 84 in somewhat rough shape and hoping to restore it for my use. Lots of rust, mostly surface on the firebox, but some scaling on the outside of the tank/cook chamber as well as the drip pan. Firebox grate is shot, and cooking racks are very rusted too.

I'm considering using a rust converter that has worked very well for me in the past, a "naval jelly" -type product consisting of phosphoric acid that reacts with iron oxide (rust) to produce iron phosphate (a hard metallic surface resistant to rust). Naturally, I'm going to clean up any residue, although both phosphoric acid and iron phosphate are used as food additives (in much smaller quantities!). This would be applied after some light sandblasting to remove any loose rust.

Does anybody have any experience with this technique, and/or would you recommend a different approach? Any/all ideas appreciated!

I'm also thinking of building a charcoal bin/basket and ash tray for longer times between reloading fuel (maybe a stoker or guru too), but that's probably another thread.
