Rad off for plastering?

remember to add a litre of X100 or similar on refill

Take it you connected the hose to a tap and flushed out the radiator - this gets quite a lot of gunk out.

I'll run the shower through it later on... ( bathroom next to the kitchen, it's a flat afterall... )

just funnel it into the rad before re-filling? or do I have to pour it into a dosing pot somewhere in the boiler?

if you can get it into the rad, or any other pipe (e.g. using a funnel and hose) without it leaking out again, that will be fine.
