Great looking Astray! Which Tamiya weathering sets do you use? Ive seen Weathering Master Set C end up making models looking great, but i always wondered how well it stays on after application. Did you seal it in with clear coat?
thanks i also like C, but my new favorite is F (titanium, light gunmetal and copper). also i've used Oil stain on D here. they are so good that it feels like cheating XD they stick to paint fairly well. and stays fixed like any paint after sealing.
and no, this is not sealed yet. still needs some touch-ups here and there.
i use valejo air colors for airbrush spray paints might work. but it's kinda harder to cover some colors with spray paints. like red. or if plastic is darker color than what you gonna use. they also give a thicker paint and it's easy to obscure some details.
enamel paints are good for traditional brush work. revell acryllics are also good for that. but i didn't like metallics of that line.
i also use tamiya weathering master sets for drybrush.
