IDF M-51 Super Sherman - tracks

For a little variety, I started with tracks. Because original Academy are so awful, I tried to put them in heavy dust.My recipe:
- base of flat black
- strong dry brush with Model Master metalizer
- strongly diluted wash made of Humbrol 113 (apparently rust color:)
- a lot of grated dry pastels in sandy, dusty colours
-gentle fog of pigment fixer from airbrush
-tread repainted with mix of Model Master metalizer and humbrol 113, next with soft pencil I gave them some shine
-tire marks are made with black crayon, smeared with lightly moistened brush
Final touches will be given already on the model.
