Hi there!
Finally I managed to make some progress. My wife is a kindergarten teacher. Her institution was expanded this summer, and now she has a new room, new colleagues, new kids, thus tons of new decoration, games and other stuff needs to be created. And we have only one hobby-corner in the house...
So where was I? Oh, yes, dirt... I mixed some sand pingments from Humbrol and light dust from AK, but the clear parts were just too smooth, pigments did not stick to them. I used an old Opel Blitz to find out how to add pigments to the windscreen while keeping it's transparency. The winner was the DecalFix from Humbrol. So I masked off the paths of the windshield wipers, and covered the rest with some decal fix diluted with some water. The clear parts remained transparent, and it created a semi-smooth surface for pigments. Additionally a thicker layer gathered at the edges of the masking tape allowing a thin border to be created by a thicker layer of pigments.
The decal fix was used to build up a bigger amount of sand and dust in the truck's bed.
The rear window was still terrible, I had to hide it somehow. When I have to work on our car, and have to put tools on it, I usually cover it with a blanket. It protects the polishing and prevents the tools from slipping down.
I used some air-drying plasticine, rolled to very thin. I left the material to get a bit dried, and with a dull knife and a ruler on the waist side I cut the plasticine to size and shape. I did it to have rough cut, thus the blanket will have an old and used look.
When it fully dried I added some 1 and 2 mm wide masking tapes, painted it with a light coat of black, rearranged the tapes, and painted again.
Finally different black, brown, rust, sand and dust colored pigments were used to weather it.
The pickup is ready:
The tools will be from Italery's Field Tool Shop, which is a pretty old kit, originating from 1980s. (

Actually it is a nice kit, with nice details, and only a few fitting issue. You can find anything here, hammers, screw drivers, wrenches, tool boxes, barrels, a generator, an old welding sett, a lifter frame, etc.
I want to use some tools, a toolbox, the welding set and the frame.

The arrangement will be something like this:
As you can see, there are some serious fitting issue with the frame, but nothing that Tamiya putty and sanding can't fix. Revell's Eisen gave a nice undercoat, dry-brushed with MIG's Rust Primer, and upgraded by some dark brown wash from MIG. Since I have no chains in this scale I twisted a couple of thick wires, and glued it using white glue. The "chain" was treated the same way: dry-brush with rust, washed with brown.
Here I am now, I hope you liked the progress.
I don't know yet how the base shall look like. How does the ground of a workshop in the desert look like? Something like this?
