Finishing all of these with highlights weathering etc is taking awhile. But I thought the basic cammo looked so good I ought to get a picture up. It reminded me of the old steel legion cammo but a slightly lighter brown. I used Army Painter Leather Brown to basecoat and then Army Painter Skeleton Bone to put lines across them. It took a couple of coats to get the colour right for both processes. Make sure you leave a few mins for it to dry a little before re-applying and practice line thickness on some paper before you double up the cammo lines to avoid overspray! The cans allow a fair bit of control depending on how hard you press.
This really is the easiest and quickest way I could find to paint up cammo that ensures every tank is the same two colours (unlike some of my older tanks where I forgot the scheme or differing layers led to slightly different shades, lame I know but when trying to paint 4 armies at once you suddenly find its 12months since your last tank got painted). Oh and one can of leather brown comfortably covered all of these tanks with multiple coats and some over, it goes without saying the skeleton bone still had over half left.
