Getting the basecoat on, blocking in the main colours and then using Army Painter Strong Tone on them left me with highlights to do and the dusty effect I have been aiming for.
I picked up some Vallejo pigments and set about making a mess of both models. Stupidly I was confident I would get the effect I wanted (or close to it) first time round. What a fool I am!
Next day, with a hot tap and a old toothbrush, I found myself scrubbing away.
Another few attempts with pigments, and I defaulted to using a drybrush. Another possible mistake at this point is that I've not applied decals yet. This may come back to be an issue later.
