Theo,
Do you mean furniture polish or similar? 

I found the places where rust was worse was the metal bends ,pivot , spring area.
it would be hard to rub wax in there, unless I pulled the springs and pivot pin which seemed like alot of work.

Metal parts on the outside are fine to be treated. Having removed the rust it shouldn't return for many years.
If you live in or by the sea it may return quicker. A small wipe of Vaselene or similar will do the trick.
But, in my opinion not necessary. My first box, even after a Dunk (sorry Pete) in the river Syd didn't really start rusting seriously for a month or two.

I was referring to external parts.  Internal parts just need to be lightly brushed to remove loose dust.  You can also remove the axle rod and clean it and levers etc if they are heavily contaminated.

So no wax needed , inside rust is done already.

I'm going to bush base side, I just need to source some bushing felt. Is there a certain thickness I should use? I guessing the thinest stuff I can get?

I do live near the sea but the rust was light and I've been here 30 yrs. The Box is 60 or 70 yrs old.
I'm not going to worry about it, unless I go for a boat ride ;)

There's a product in the UK made by Hammerite called "Kurust" it is a thin white liquid which turns rust purple then black (phosphatises it to the less reactive iron oxide) it skins then dries - I suspect this element is a PVA or similar. It leaves the rust neutralised and encapsulated, normally painted over, for internal work it would be fine as is.

Tis not cheap but a small bottle lasts a long time (don't contaminate the bottle contents by dipping the brush back in)

I use it where mechanical rust removal is not straightforward, especially where separating wood from iron is likely to cause more damage than its worth.

Not had a melodeon bad enough to need treating but wouldn't hesitate to use it (not on reeds I hasten to add) sold by most ironmongery / vehicle fettling requisites outlets.

Thanks Richard,
I saw some stuff similar at my local auto parts store but didn't like the idea of turning things black
and was'nt sure if it left unwanted residue. I could use a big tub of it to dip the bed of my truck in though :(

Bill Gates might need to think twice about a chassis sized bathfull  ;) I suspect it would darken rust stain in wood such as pallets and cloth pads, my recent Liliput has some around the pads, I might experiment and let you know the result.

If exposed, a rub down with steel wool and then a coat of lacquer will hold any further ingress at bay for a long while.

So I got the bushing done  (:)  I'll post some pics soon.
two questions:
Do the bass buttons just push back on? (no glue )
my guess is yes but figured I'd ask.

what is the material used for padding (limiting) treble buttons?

Any tricks (no april fools please) to putting buttons on bass side?
The holes in new buttons seem a little smaller than the originals and it's taking a lot of pressure to even get them started.
I'm holding metal rod just behind the hole in the case to support and I put a little piece of wood behind pivot so metal arm does not push back as I push.
what say you?

I always remove the metal rod, clamp it in a vice then lightly tap the button on using a piece of softwood between the hammer and the button.

They are a very tight fit, you could try using a crew driver blade that is no wider than the end of the rod. Press the blade into the hole in the button to enlarge it. This will make the button easier to fit to the rod.  Go carefully though because if you enlarge the hole too much the button may fall off.

Thanks Rees & Theo!!
I did the remove the arms and put in a vise trick worked great.
I just got done putting valves the on the reeds so, I just need to wax them. Then send it out for tuning.
Still debating the waxing methods, is it ok to put all reeds in place then wax all at once or is it better to do one at a time?? I have the little nails that hold them in place some what but there is a little play.

Throw the nails away! They are just a nuisance.  My method is to pull all the reeds in place, then tack them in place with a drop of wax at each end of each plate.  Then reassemble the box and play all the buttons to check the reeds are all in the correct positions! Then do the full waxing.
