    Hi all I'm not the OP but moved into a new place with cast iron rads in Anthracite Grey so decided to paint my HR92 as they didn't look too great in bright white against the grey. The rads are powder coated in gloss RAL7016 so I bought a spray can of the same colour. I removed the top knob and the bottom wheel, masked the display off and rubbed the casing down with 1200 grit wet and dry.
    A couple of coats left me with the following, I'm very pleased how it came out:

    Looks much better than white. I found that even when unpainted the internal temperature sensor doesn't work very well on cast iron rads as there is too much influence from the direct heat of the radiator, so am using an external sensor to get a sensible temperature reading. I haven't yet compared painted vs unpainted as per the previous discussion in the thread, but will try it out and see what the results are, even though an external sensor is the only real option anyway.
