The whole hammer is true metallics but some parts have colour glazed over it just to add extra interest. What do you define NMMP ad?
The backpack is sponged. I start with the Base colours - dark blue to a lighter blue at the top. Then sponge a very light blue onto the areas I want to be aged (this acts like it's the primer coming through below the blue. I then sponge a black brown mix onto the light blue sponged areas but a little smaller so that the white is still visible at the edges. Then I add depth to the black brown by adding brown oranges. I then give the whole lot a wash of gw earthshade (the brown wash which I can't quite remember if that names correct). Finally I pick the edges out with a silver. Really it's pretty straight forward.
