What's the best way to key the paint on steel panel radiators before

None of the above.
Use steel wool and lightly rub down, especially inside the grooves


I want to use emulsion to match the walls and then cover with
International Radiator Clearcoat.

If you rub too hard and take it down to bare metal, rust spots will show
through emulsion, touch these up with oil based undercoat prior to
emulsioning


Can you really emulsion a radiator and hope it stays on?
