Would need to be a huge barrel ..... the ramps are over 1m long and as per the video they need to be suspended not sitting on the bottom.
I'll go with neutralising the rust

It can be applied direct to rust, but it won't stop it.......nothing will, but a rust converter will put off the inevitable for some time.
It's just fine for what you want.

I have KURUST it's a well proven rust converter, and will treat all of the metal with this before painting
No actual need to suspend them, if using a plastic barrel, and you could do one end, then the other.
All that is needed, is the two metal parts, to be insulated one from the other, making the water solution the only conductive path. +ve connected to your 'sacrificial' anode, the electrons flow from -ve/ your ramps, along with the rust, to the anode.
The process works best, across the shortest path between the two metals, so worthwhile rotating your cathode (ramps), 180 degrees in the solution, at half-time.
Once done, your sound metal remains, and all the rust is gone. One improvement I found worthwhile, was to add a 12v bulb in series with one of the battery connections, just in case your two lumps of metal, happen to make contact.
I appreciate your explanation, but I won't go that route, (no tub big enough, no 20A charger)
I have removed all loose rust with severe power wire brushing.
I will apply a rust converter, and then 2 coats of Hammerite.

Which is just phosphoric acid, cheaper if simply bought under its chemical name - phosphoric acid, than under a trade name.
I realise what it is, I could get 500ml of KURUST delivered cheaply next day ..... was happy to pay £6
Nice pretty colour where it has been active.

My, possibly incorrect, interpretation of "loose rust" is not rust that simply comes off when you run a dusting brush over it but rust that will come off if you run sandpaper over it.
I used rotary brushes in a drill … so got rid of anything loose.
