Come to think of it, I think I'll have to airbrush them after all. The chibi-kits are much less detailed than your PG one, and a piece that's supposed to be made of multiple colours can/would be moulded in one only - so I'll have to break out the brush for that.

Then there's also the issue of having to spray the kit in a gloss coat first before I can panel line it, and only afterwards apply the matte spray. The panel line ink doesn't go well when the surface is porous/bumpy like with the matte finish.
