Thank you for visiting and your kind words, gents.
If can be useful, this is the sequence I followed for tracks making (using the original plastic tracks from the box): Priming with Tamiya matt aluminium, then the whole AK set of rust effect colours, from the darkest to the lighter, all brush painted trying to cover less surface with each shade. Coarse spray of dark brown and wash with the same highly diluited colour. Finally drybrushing with Humbrol silver. After this process further random washes with very thin ochre and brown were applied with sprinkling of dark pigments (burnt umber, burnt sienna and Cassel earth).
Body weathering was made with oils, following magazines and Youtube tutorials.
