This was my original brute color scheme. I was going for a lot darker armor at the time, but when I painted one again I like the result of the new formulae better.
The result was pretty popular and I decided to make a small tutorial for anyone who is interested in doing something similar. Its super simple and only requires three "paints."
First I painted the silver over the black undercoat. One coat did it and the paint is for airbrushes so there was no need to thin it.
After the silver dried I used a large brush and covered the silver in undeluded Oiled Earth wash.
After the Oiled Earth dried I used the same large brush to apply a Black wash. One trick I used here was after I applied the Black wash I used my finger to wipe off the black in raised areas in a similar manner to dry brushing. This technique looks best with a matte finish applied after.
