Thinking of a method i can follow for all my future tanks and i think i just came up with a good one for my Sturer Emil.
1) Coat the base coat with tamiyas clear varnish. (The base coat being tamiyas german grey.)
2) Apply a dark grey filter over the entire model seem the paint is abit "light"
3) Apply a matt varnish. (Vallejo acrylic)
4) Oil pin washes
5) Rust and Dust on the tank itself.
6) Dry brushing to bring out the detail.
7) Hair spray technique on tools and floor boads inside the tank.
8) Mud and dirt on road wheels and tracks.
So what do you think? Have i got it all correct? Give it a shot?
Thanks,
Callum.

P.S
Instead of using tamiyas acrylic clear varnish, and then vallejo's matt varnish, what if i used vallejo's satain varnish? Not need for a matt coat then?
