Stealth Wheel paint touch up paint

[NobleSteed]

My 720S has the lightweight 10 spoke wheels in 'Stealth' finish. I am sure somewhere on this forum someone had managed to find/purchase/source touch up paint. I only have a couple of tiny chips on the edge of a couple of spoke so it is not a case of wheel refurbishment, just a tiny touch up required. Can anyone provide any help?

If you do find a suitable paint then pls let me know as I have some bad stone chips that need touching up!
