I finally got my hands on a box of Nighthaunt from my local store. I also picked up a bottle each of the new Citadel technical effects Hexwraith Flame and Nighthaunt Gloom.
Incidentally I actually bought this set of 10 models to use in Frostgrave, not Age of Sigmar. I wanted to have some undead for Frostgrave that were more on the supernatural ghostly side. And I have to say, GW really did an amazing job with these models. They are spectacular.
I started the models by doing a primer spray coat of Army Painter White. Then I did a thin coat of Vallejo brush-on primer.
I applied the Citadel technical effects right over the white like you would with a wash. I have to say that these new effects live up to their hype! It works really well. And it's indeed true as GW claimed. You can do nothing but a white base coat and just wash over it with this stuff, and the models could be left just as is!
I was also pleased to discover that these are indeed a "one pass" wash very much like Secret Weapon Washes are. They put down a very strong wash over white, you have to be careful not to put on too much. In fact the blue one, Nighthaunt Gloom, is actually a bit too strong straight out of the bottle. You could add a bit of water to it and it will still work very well. The consistency of the technicals is very much like Secret Weapon's washes: a milk-like consistency with a pigment in the bottle that's more opaque than a standard wash.
Here you can see several different attempts at using the technicals. On one model I used both technicals just to see how a blue/green shade would look. I also did some white drybrushing near the tips of all the ghostly shapes to try to do a transition look of ghostly to tangible.
On the second set of five models I'm going to use both technical on the same model, where I use the blue on the cloak and upper half of the model, and then use the green on the lower parts of the ghostly shapes for a dual effect.
Here's the pics of what I've done so far!:
