Honest ..
The Armour is pre mixed in a pot , with vermin brown.
Once the undercoat and bases are done, then you paint every model at once,.
undercoat is army painter grey, then wash heavy black and brown...
Basecoats: so Tallarn flesh each man, then armour on each man, then blue cloth, then browns, then orange, then wash all of them, use hair dryer at every stage to dry,
wash again,
highlight is simple also
job done
