V8V brake caliper paint?

[Dungman]

Folks

I have a couple of small chips that I would like to touch in. Is anyone aware of a source of touch up pens or a paint code? I have the grey calipers as per the below image borrowed from Google.

Many thanks

I'd be very interested to know this too, and if there is a specific paint code/name for the silver brake calipers to obtain a touch up kit....

Managed to tt one of mine with a punch TWICE when removing pad retaining pins last year, and another got clobbered by a wheel going back on
