Had some time to do some quick weathering and chipping (please excuse the dodgy photos)...
As well as added grim I have done some chipping in a dark purple-grey around the edges and areas which I guess would see a lot of wear and tear.
The thing to remember is that this tank depicts a vehicle which saw action up to the final stages of World War 2 - in fact one which took part in the final Battle for Berlin - so it will be quite war weary.
Hopefully I haven't over-done the touches of light rust and scratches.
I haven't perfected a good means to do dust yet, I would like to do some work with dust effects in order to tone down colours and flatten the finish. I may yet try to add some dust using powders.
NEXT: Adding mud to the underside before attaching the tracks.
