i've used metallic black, silver and gunmetal spray paints mostly. and gold markers on some parts. also drybrushed some tamiya weathering master silver and rust.
it was mainly a test of how spray paint works on gunpla. and i'm not very fond of it >_> sure it's like painting in lightspeed compared to airbrushing, and no cleaning afterwards but it congeals, leave bubles, explodes and all kind of nastyness that needs attention afterwards >_>
