Preparation and detailing
This model was washed in warm water with simple green used as the degreaser. It was soaked in the mix for a few hours before the parts were carefully scrubbed with a tooth brush. The parts were then left out to dry overnight on a tea-towel.

I then cleaned off the mould seams where possible. Forgeworld has come a long way since the first models I bought and mould lines are few and small, little to no reconstruction work is required on the detail of this model. The worst mould lines are on the trench crossing rails at the back, where the mould has not line up perfectly. However it's not so bad that filing can't reduce it to manageable proportions.
Nothing that is on a sprue is clipped off. Parts are left on sprues for ease of handling during spraying, and to keep parts together and not lost in my carpet!

I am not doing any ultra detailing on this models as it is already pretty stunning out of the box, besides the Real World^tm, has really done a number on my paining time over the last half year and will continue to do so for the foreseeable future.

Undercoat: Halfords Grey Primer
With all of the bits clean and prepped I spray the parts with Halfords Grey primer. This is a car body repair primer and has no trouble sticking to the normally hydrophobic resin used by GW. It forms an intermediate layer between the hydrophobic substrate (the model) and the wetter GW chaos black spray.

Basecoat:
Undercoat as usual with Citadael Spray Chaos Black, working in even strokes 8in from the surface to get a light even coating.

Top Coat:
All of the spray work is done in Vallejo: Model Air colours.  It is Basically done in Four stages:
 - Top Coat
 - Mapping
 - Camouflage
 - Unit Campaign markings
 - Tracks:

Firstly the Tracks (Still black) are masked off with  Tamiya Masking tape and the body of the model is sprayed with the top coat of VMS:

Then the Mapping with Vallejo Model colours, Various shades of the topcoat were created using VMA: mixed and thinned with VGC: Pale Flesh; VGC: Snakebite leather VCG:Burnt Umber.  These various mixes were painted onto the vehicle in large Continents.  The Top coat of VGC was then sprayed over the model to blend in and tone down some of the variations.

Then the Camouflage pattern was sprayed on free hand with VMA: Again in large continents.

The Masking was then moved off the tracks to the body itself around the tracks and the tracks given a coat of VMA: Burnt umber.
