This short tutorial demonstrates some simple techniques to use while applying washes from the Nitroline.
You can use a wash straight from the bottle or thin it on a palette prior to application.
With this example I applied a general wash over each of the wheels focusing more on the details like the grooves and fasteners.
Let the wash set for a few minutes, then remove the unwanted amounts using a clean brush and thinner.
Paper is great for quickly wiping away the excess wash because it does not absorb as much of the thinner from your brush as a paper tower would for example.
The lower three wheels display how these simple techniques can easily allow you to apply fake shadows and added tones while also highlighting details.
