With construction more or less finished, time to concentrate on final paint - weathering.
The paint story so far:
Acid 8 etch prime
Oxid rot RAL 3009 primer
Camouflage: 2/3 gelbbraun RAL 8020 and 1/3 graugruen RAL 7027 (Xtracrylics)
Citadel Purity Seal satin varnish to seal
Various washes from Promodeller and AK Interactive to highlight detail and shadow
Vaious pigments from Promodeller to fade, apply dust, discolour. The Promodeller pigments are easy to use, come in generous quantities and have a very fine grain size, so they don't dry streaky. Mig Pigment Fixer is used to complete. The only drawback with pigments is their capacity to dry in shades which are generally much lighter than when wet. The hue remains constant so the effects can be tested in a small area before the full application.
Filters from AK Interactive: Light grey, DAK desert yellow and a darker yellow. Filters are very simple to use, just a heavily diluted mix of enamels which unify and vary the tones of a disruptive camouflage. The paint is translucent and infinitely variable. The effect is seen where I've missed a bit on the turret overhang:
Next comes the fading step. Fading is done using oil paints to replicate the effects of sun and rain. It's best to squeeze out some oil onto card to absorb some of the unwanted linseed oil. This allows the paint to dry quicker and with a matt finish. Various shades of yellows, ochres and browns, with some white and blue on the grey, are applied as dots and then dispersed using a wash of turpentine:
Oils can also be used to create highlights and shading and since they're translucent, the underlying colours can be preserved:
Now for the bit that's easily overdone - chipping. I used Vallejo Model Colour 70822 German Camouflage Black Brown on the yellow and on the grey, a combination of the base RAL 8020 and then the black brown.
Final stage will be some very limited dust, rust and mud. The Tunisian campaign over the winter of 1942/43 was a mudbath and a lot of contemporary photos show running gear heavily clogged with mud but it needs a bit of restraint.
More to come. Regards
