Firstly I always undercoat in black using the Games Workshop sprays. Black as a pose to white undercoat means that if you do miss a bit, say under the arms, then it just looks like shading, where as the white undercoat stands out like a sore thumb! Many people swear by white and who am I to criticise, the black does dull the colours slightly but I don't tend to go for parade ground troops anyway and I like to speed things up as much as possible. I never undercoat using a brush, the time taken would do my head in!
I tend to use plastic bottle tops with Whitetack (not Bluetack as it's not as tacky) to save handling the figures themselves.
Anyway, first picture:
Strip of figures with the first coat of Dk grey on the tunic.
Brown belts, metallic silver musket barrel and bayonets added.
The finished Languedoc Battalion based using 'Basetex' brown and green and then highlighted. Figures varnished using Matt Games Workshop spray.
That's all for now, hopefully a 10mm WSS battle report with pictures to come soon.
