I've done a couple of Bloodbound with it and I've had a fair bit of success with careful application of a single coat. Not tried the new medium yet since all the paints I've tried have actually worked fairly well out of the pot (neutrals and the Flesh Tearers red). The Black Templar highlighted with stormhost silver creates a really nice black metal effect. Not a replacement for boltgun metal but a very easy way to get a fast dark metal tone.

Tbf, chainmail under a cloak could be anything from death to a 40k primarch.
