- Paint chips on the metal were simulated using Vallejo Model Color “German Camouflage Black Brown” (70822), applied with a sponge or fine brush. Paint chips or damage on the wooden parts were simulated using Vallejo Panzer Aces “Old Wood” (310).
- The exhaust was painted with the various colours of the LifeColor rust set.
- The engine was drybrushed with Citadel “Leadbelcher”.
- Before further weathering, a 1:2 mixture of Mr.Color “Clear Gloss” (46) and Mr.Color Leveling Thinner was sprayed over the entire model.
- The entire model was washed with a dilute mixture of Winsor & Newton “Raw Umber” and “Lamp Black” oil paints (ratio about 5:1) in enamel thinners.
- The engine and panel lines of the truck were brushed with AMMO Oilbrusher “Starship Filth” or “Starship Bay Sludge” and the excess removed with cotton bud.
- Vertical streaks on the cab were added with AMMO Oilbrusher “Starship Bay Sludge” and “Rust”.
- Some rust was added to parts of the chassis using a wash of AMMO Oilbrusher “Rust” in enamel thinners.
- The headlights were painted with Abteilung 502 “Silver” oil paint.
- The tilt was dotted with the following oil paints: Winsor & Newton “Raw Umber”, “Payne’s Grey”, “Permanent Magenta”, “Transparent White” and AMMO Oilbrusher “Medium Grey”, “Olive Green”, “Yellow”, “Black”. The dots were blended using a flat brush dampened with enamel thinners.
- The entire model was sprayed with a 1:2 mixture of Mr.Color “Flat Clear” (182) and Mr.Color Leveling Thinner.
- The wheels and chassis were sprayed with a 10% mixture of Mr.Color “Tan” (44) in Mr.Color Leveling Thinner to give an initial impression of dirt.
- AMMO “Europe Earth”, “Dark Earth”, “Rubble” and “Brick Dust” pigments were brushed onto the vehicle and wheels, to varying degrees, and fixed with AMMO “Pigment Fixer” (A.MIG-3000), added by brush.
- Abteilung 502 “Bitumen” (ABT004) and “Engine Grease” (ABT160) oil paints, in varying dilutions in enamel thinners, were added to parts of the vehicle, to simulate stains.
- There is a photo on page 8 of the book Soviet Trucks of World War 2 (Kinnear, Jim and Vollert, Jochen, Tankograd Publishing, 2009) of a GAZ-AA (the four wheel version) which had been converted into a “propaganda vehicle”, with the tilt covered in posters and a picture of Stalin. As I happened to have a bunch of such items by a company called Duplicata, I thought it would be a decent thing to recreate. As this model is going to be included in my Berlin diorama, you could imagine such a vehicle being used, both for the attention of Soviet soldiers and the locals.
- As part of this diorama, I plan to surround this truck with figures and have in mind one to be sitting on the bonnet, but they will have to come later.

No one is going to say that this is a sophisticated kit! It no doubt contains inaccuracies and simplifications, but it suits my purpose – as part of my Berlin diorama. I added some tarpaulin, rolled up stowage and tilt repair section – using sculpted green putty – which I hope will make more sense when the model is finished.
“The three-axle GAZ-AAA was developed concurrently with the mechanically identical GAZ-AA … The GAZ-AAA was used by the Red Army throughout the war years as a general service truck and as a base vehicle for a multitude of specialised variants.”
