Here's a step by step guide on how they were painted.
Though the rulebook uses the current Stormtrooper models, I have decided to use the Cadian Kasrkin as the basis for my models. Here they are in their current unpainted (yet built and based) state.
Here they have been sprayed with a white undercoat
The next stage is to paint the base uniform colour.
Though I wasn't happy with my test paint scheme with my assassin I decided I would use the basic concepts with these models. The first thing I did was give them a coat of Desert Yellow.
This is quite a watery thin paint compared to other Citadel paints, but was just like thinning any other Citadel paint with water without actually needing to do that.
Here is the entire squad basecoated. I have left the boots alone, as these will be painted Scorched Brown.
I do like these models, they are well sculptured and look the part.
