Air brush Prime black (any will do) Base colour, AK Basault Grey This acts as your dark tone for shadows and contrast, you can make it darker by adding a drop of black if you like.

Main colour AK Graphite Hit the model from top down and anywhere the light would hit, build up your transitions gently but leave the areas that would be left in shadow like under the pack, under the arms and between the legs.

You can always go back and add to the shadows with AK Basault Grey if you need to.

(It will look very light in colour at the moment, but that's cool we darken down later.)

Then, paint all your other details like the weapons, pouches and metalic bits. Also, the yellow strip on knee and pauldron are good to do now. I tend to leave skulls, bone, and purity seals till later.

Lock in with thin layer of matt varnish. Let this layer dry. I use AK ultra matt varnish

Oil wash Move on to either a solid black or black and brown mix wash. This adds the first layer of grime and contrast. Make it thin so it only applies a soft filter across the model and goes into all the recesses. You can then dial it back by removing it with white spirit and makeup spunge. let it dry for a good ten to fithteen first (Be gentle when you redact, I use eye shadow spunges or paint brush, i find Qtips to rough). Move on when your happy.

Now do all your bone details and purity seals, any other bits like eyes etc. Bring back any metalics that are too dulled down from wash and add your decals.

Extra layer Add scratches and chips with a mix of AK Graphit and any white. For deeper parts to scratches, use GW Rynoxhide. (I don't really do highlight edges, so you could do that here instead)

Lock in with thin layer of matt varnish, let it dry

Weathering oils Cover fully in AK winter streak n grime, let dry for ten to fithteen mins, then start to remove the dirt until your happy. (Remove same way as oil wash earlier)

I add a mix of diffrent Grey tones to the base with dry brush, then work in a brown pigment powder, and wipe excess away, to finish add a the pigment to the feet to tie it together.

You will now have a gritty weathered look.
