Here are some work in progress shots of my command vehicle used in my Not DKK Army. Vehicle by Ramshackle Games from the recent Kickstarter.
Undercoat and the start of weathering
Weathering finished and dozer blade.
Rubbing away the white paint. I used the Hairspray Technique for this. It is a bit disheartening to spend hours painting on weathering for it all to be painted over.
Masking for the blue paint
Blue paint applied
Cutting the masking for the black stripes. This camouflage scheme was inspired by the film, “Inception”.
The original design
Black stripes. I wasn’t as successful as I had hoped with the masking and had to do a fair amount of retouching.
Start of muddying up the dozer blade. I used weathering products from AK Interactive.
And the finished result
genuine grumpy old tin 
Wonderful paint job! How did you do the mud effects?
The tracks were painted with, AK Interactive: AK721 Rusty Tracks and then washed with AK724 Dry Light Mud. When dry a pencil was rubbed over it to simulate bare metal. This gave a very satisfactory look.
For the dried earth and mud I used AK Interactive: AK017 Earth Effects mixed with some fine river silt. And for the mud AK016 Fresh Mud, again mixed with silt. This does rub off a bit on your fingers, so I will be applying a coat of varnish to fix it. This then will be followed up with some gloss varnish on the patches of wet mud. I would recommend using Humbrol paints instead of the AKs as you will get the same result, probably for less money.
