Decided on Vallejo 74.604, 70.887 and 70.872, went for a wide spread camo as for some reason my 0.2 airbrush wasn't playing nicely, so went for the 0.3 was called up (had a few schnapps by then, so looked okay to me)!
To my surprise the rubber tracks worked well and in fact no adhesive was needed to keep them together. Washes were made with Humbrol weathering powders in a Decal Fix solution, easy to adjust effect with moistened cotton bud. Didn't go for caked on mud just dust.
