Next up it’s the low lights. Shadow Brown and Cobalt Blue are used here, note the areas where the oil paint is places, along raised detail in shadow areas and along panel lines. This effect will enhance contrast by creating false shadow, also it adds to the grime.
Again the oil paint is blended, first with a slightly damp flat brush and then a dry round brush.
Here is the finished effect on the centre panels. Note it’s very subtle but that is exactly what we’re after.
When you’re using this effect try and use a bit of thought to how the real aeroplane may have weathered. Here I am using a heavy effect of lightening the 2 outer panels but I painted the centre panel in a darker tone to simulate a new panel hence the fewer dots here.
The Hinomaru doesn’t escape. Red and Mid Rust are also used. Note how the paint has been applied along the surface detail, this will help to distinguish panels and create a more interesting surface for the eye to look at.
Again oils are used to create highlights and shadow to pop out the surface detail, in this case the wing root fairing.
