- Tamiya “Soot” weathering powder was added to the area of the exhausts, using a cotton bud or rubber brush. This was followed by flicking a mixture of Abteilung 502 “Engine Grease” (ABT160) oil paint and Humbrol “Gloss Cote” in enamel thinner onto the same area, to simulate oil and other substances in the fuel.
- The metal tools and barrel end were lightly brushed with AK Interactive “Dark Steel” (AK086) pigment.
- Dilute mixtures of Abteilung 502 “Engine Grease” (ABT160) and “Bitumen” (ABT004) oil paint in enamel thinner were flicked from a brush onto the surfaces of the hull and running gear, to represent the subtlest stains or patches.
- “Engine Grease” oil paint – dissolved in enamel thinner to a much higher concentration – was added to parts of the running gear, certain wheels (to represent leakage from a seal), hatch hinges and parts of the engine deck to represent older oil stains. Once dry, a similar mixture was prepared and Humbrol “Gloss Cote” was added to it, to represent newer oil stains.
- “Bitumen” oil paint – dissolved in enamel thinner to a much higher concentration – was added around the fuel filler points on the engine deck and casemate to represent older diesel stains. Once dry, a more dilute mixture was prepared and Humbrol “Gloss Cote” was added to it, to represent newer diesel stains.
AMMO pigments “Europe Earth” (A.MIG-3004), “Airfield Dust” (A.MIG-3011) and “Light Dust” (A.MIG-3002) were added dry by brush separately and somewhat randomly to large parts of the running gear, tracks, wheels and hull. A 1:1 mixture of pigment fixer and enamel thinner was added by brush to those parts to seal the pigments in place. In some parts, such as the lower front and back hull, where dirt and mud could be expected to be sprayed, I repeated this process. The aim here was to end up with dried mud of some colour variation.
Those parts of the track in contact with the wheels were treated with a 2B pencil. The outer side of the wheels and tracks were treated with AK Interactive “Dark Steel” (AK086) pigment.
- Fruilmodel tracks (ATL-14) were linked with Albion Alloys’ 0.5 mm brass rod – 85 links per side.
- Treated with UMP “Ultimate Burnishing Liquid”.
- A dilute mixture of Winsor & Newton “Raw Umber” and “Lamp Black” oil paints in white spirit was used to collect in the recesses of the tracks (especially if there were any small areas left shiny).
- A dilute mixture of Abteilung 502 “Light Rust Brown” (ABT060) in white spirit was flicked from a brush onto the tracks to give the impression of rust spots.
- AMMO “Oilbrusher” oil paints (“Dust” A.MIG-3516, “Dusty Earth” A.MIG-3523) were dotted on the much of the horizontal surface, underside and running gear of the vehicle, which had previously been dampened with enamel thinner. Next, using a round brush the oils were dissolved and “melted” onto the surface, particularly to collect around raised objects or recesses. This was my first pass at achieving dust and dried earth effects, although I left a few areas deliberately less dusty.
- Following this, the same oils were dotted on the sloping sides. This time a flat brush was used to draw them down the sides, in the hope that this would simulate rain marks or dried streaks.
- Once all was dry, everything was sprayed with a 1:2 mixture of Mr.Color “Flat Clear” (182) and Mr.Color Leveling Thinner. Thus, a matt surface was ready for the addition of pigments.
