White paint for Oil Pressure Gauge needle ?

[Nickleback]

Hi all,
I have now replaced my electrical oil pressure guage for a mechanical one for reliability reasons, but the white paint on the instrument needle is yellowed and discoloured.
Can it be cleaned back to white or is it best just to re-paint it ?
If so, what's the best paint to use for this job ?

I use some of my Tamiya modellers paints..water based and Matt..watered down and a fine brush
Hope that helps

Thanks Jonathan,
Sure does, the faces are interchangeable, as is the besel and glass, so this solves the last part
