Thanx guys
Brian: I use Gunze 303 for my soviet vehicles, its quite light green but I darken
it with a black post shading and a black/brown oil paint waches.
I usally paint the tracks black for starters, give them a light dust layer to
contrast the following dark contrast washes. The whole supension is given
multiple layers of different oil paints (black, Vandyke brown, burnt unber and
yellow ochre).
The trick is to dare to go over the top with the weathering, the clever thing
about oil paint is that it dries very slowly, if you overdo the weathering you
simply apply some more thinner and remove some/all of the oil paint and
start over.
Kind regards
