Piston coating?

In the process of doing a top end rebuild, so thought I would tidy up the piston crowns whilst they are out. Having removed the carbon, there appears to be a grey coating on the top, and sides down to the oil ring. Is this discolouration or a coating? Is it ok to remove it, ie polish the pistons?

As far as i know thats discolouring. No coating on the ZXR's pistons as far as im aware.

to be read as "Polish away if you wish, but Robb takes no liability if it goes tits up"
