Thanks mate, i'm a bit of a brush snob to be honest. I used a Neef pure sable size 4 flat and size 8 flat to laydown the Games workshop Leadbelcher base coat for the dark grey, it needed 2 coats.
For the top recess base coat on the thighs I used a Neef pure sable size 1 flat.
For the bigger panels on the chest I the same size 1 flat, for the edges and finer parts I used my Windsor and Newton Series 7 size 0 to lay down the Xereus Purple and the custom brown mix.
To pick out all the tiny bits in the the thighs used a Windsor and Newton Cottman 333 Rigger size 0. I needed the longer bristles so it didn't stuff up the surrounding bits (i just used the tip).
I also used this for the Tamiya Copper and Metallic Blue on the chest and the flat yellow.
There's ALOT of layers to the paint, to make the Clear Red brighter on the chest just next to the insignia I used the size 0 brushes to put down Tamiya Flat Aluminium and then went over that with the Clear Red.
The most important thing with this work is to keep the points goods. Between each colour the brushes were washed with water, then Windex, then water again and then The Master's Brush Cleaner and Restorer to shape the point back before being dried upside down to used with a new colour. I generally have 3 of each of my brushes so they have time to dry between me switching colours.
