ISU-122 build – Part 13:Stowage

  • I selected various bits of stowage items from my store, to represent the crew’s items and perhaps things they had picked up along the way.
  • These were painted with Tamiya and Vallejo acrylics.
  • Once protected with gloss varnish and then Mr.Color “Flat Clear” I weathered them using the same oil paints and pigments as previously.
  • Not shown in the pictures but added to the vehicle later were some spent shell casings (RB Model 35p29), weathered by the action of a lighter flame.

ISU-122 build – Part 12:Weathering (final effects)

  • 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.
  • I didn’t like the look of the clear part for the headlight and had no suitable replacement, so went for the option of the light having been somehow destroyed.


ISU-122 build – Part 11:Weathering (oil and fuel stains)

  • 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.


ISU-122 build – Part 10:Weathering (mud)

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.
