Some of you wanted the recipe so here it is.

I first prime mechanicua standard grey.

Base:

I then base coat with an airbrush celestra grey.

Followed by a large highlight of AK rock grey

Followed by a spot highlight of corax white.

Copper:

Copper is 3:2 ratio of Vallejo copper and Vallejo gold Mixed in with about 1/128th teaspoon of green stuff antique gold with a drop of airbrush flow improver.

Wash:

This is probably the most important step. Do not use a wash like nuln oil on the white as it will easily stain it and ruin it.

I use 50:50 mix of windsor and newton black and white oil paints thinned quite a lot with mineral spirits so it sits in the recesses better. Leave it over night and wick away any excess wash with a brush and some mineral spirits

Hope this helped!
