The paint started with acrylic metallic gray all over after masking off with much liquid latex masking fluid.
From there the tiny bits o' tape were placed on in semi- ramdon fashion.
About a hundred or so bits later, a coat of acrylic dark sea grey was airbrushed on.
A repeat of the last bits o' tape performance and a coat of acrylic dark to meduim colour grey.
Same again...
And final coat of acrylic mid grey to finish.
