@Jegind Black undercoat, Mechanicus Standard Grey, Devlan Mud wash, then restore MSG, highlight with Codex Grey (Dawstone in nowadays).
On the lower pic we can see (if use some magnifiers ) little scratches done with 1:2 Chaos Black:MSG mix and pure Mithril Silver over it. Maybe some more photos tomorrow, as I've succeded to "scratch" a whole squad today.
