Shawker - good job on the Tiger II, I like the added touch of the netting on the barrel - and grats on the completion.

Thanks all, for the comments on the tracks. I'll try my best to describe what I did, but bear in mind that it was an experimental process as I've never done them like this before, and until now, never had all the variety of choices that can be found these days.
First the products, I think most are fairly visible in the photo.
- the two sets of links were sprayed with old track from the LifeColor set. The tracks were made of black plastic, so I let this work to my advantage and did not strive for a solid coat of paint.
- next, I cut two narrow strips of masking tape for each track length. This represented the area where running gear did not disturb the track surface. Over this, I first wet/dry brushed MiG's track brown followed with LifeColor's reflective agent (basically a dark metallic powder). I Used Tamiya's acrylic thinner to give the dry brush a better bite, it also helps seal the powders.
- removed the tapes, and I think at this point I wasn't satisfied and proceeded to cut six lengths of masking tape for each track, representing where the road and forward gear wheels touch the surface. Over this was wet/dry brushed LifeColor's dry dust.
- the above tape also protected around the guide teeth, which were done next. Top halves were painted with AK chipping colour. Over this was applied some of the track brown powder, and lastly, the tips of the teeth were wet/dry brushed with dry dust.
- masking tapes removed, had some touching up to do. Also streaked some of the chipping colour on track surface were the outermost road wheels would run.
//////////
- the opposite side, that touches road/ground surfaces, is much simpler. A wash made from MiG's light dust was applied. This powder is odd though, as it has a green tinge to it. Not happy with that, made another wash to tone that down - created from Flory's sand and light dirt.
- dry brushed the reflective agent, followed by a lighter application of Tamiya's metallic grey.
- a final thin wash over this, from the left over Flory mixture.
