Painting was easy, I managed to paint all 6 Russ tanks in one day using this simple method.
I used Army Painter Uniform Grey as undercoat, as per all of my guard models. This was done a day or so in advance, so maybe me claiming they were all painted in one day is a bit of a stretch!
I then painted the Blue bits, Fenris Grey [as this is the same colour I use for my guard models armour plates/helmets].
The guns were painted Orkhide Shade and Boltgun Metal
The tracks and exhausts were painted Tin Bitz
The yellow is Iyanden Darksun
Then I drown the model in as much Devlan Mud as I can get on it, this does all my shading. highlighting etc, and it obviously collects towards the bottom of the model, giving me a kind of weathering/dirt and grime effect.
So far my Guard army has used 4 full pots of Devlan Mud. It isn't working out an especially cheap painting method! I think for future armies, I will be using an alternative shading method, perhaps an Army Painter Quickshade, which seems considerably cheaper than GW.
Finally, apply the transfers, then use matt varnish to ensure the transfers dont keep coming off.
Some of the models have other steps, primarily if they have plasma weapons, but it is a straight forward process.
