Hi All
The dust on the plane is make to have a good weathering.
If you see some pictures from the real plane in operation, you can see how the plane is durty.
This dust is not in rust but in flat earth. The pictures changes the initial color.........
My technic is to make some effects to have a global view when the model is finished.
The plane that you see is not finished. The weathering will make it
possible to give relief to the unit.
Let us not forget that these planes were located on dusty
and muddy grounds.
Friendly
