Hi all,
this one started as an exercise object for the hairspray technique. I grabbed an old model, the Tristar 38(t) kit, and used it as base for a little fun. I painted directly over the original paint job and applied a thin layer of acrylic white. After a few minutes I removed some parts of the whitewash and started mapping and filtering with oils. 
Here is the current state , just a few more tweaks and I will call this one complete.
Any comments and suggestions are highly appreciated. 
Hope you like it so far,
Manuel
The original model. I removed some details like the Rahmenantenne for the painting process:
A layer of HS, followed by acrylic white:
Chipping with a stiff brush and water:
Added darkbrown washes and a first mapping:
Painted some parts for the vehicle:
And this is the progress so far:
