Automotive primer (more quantity for less money then hobby primer), was applied with the airbrush so no details were lost. First, I give it a thin coat just to cover the resin, then, after 15min, I give it a thicker coat, more "wet", so it accumulates on the little scratches left behind by the sanding during the building process. After drying overnight, I sanded it with 1000 grit sandpaper just to remove dust and even-out the surface.
I've already given it an undercoat with LifeColor Black + Tamiya Thinner and the Panzer-Gray will follow. More updates soon.
