Just about to build a Tamiya 1/100th Lightning and they state using AS12, Bare Metal Silver, spray for the overall finish. Is their a MA alternative maybe? I like Tamiya paint but I find their metalics a bit course grained.
Or even Games Workshop Citadel metalics. Mithril Silver for aluminium and Chainmail for polished steel/darker aluminium. Bolt Gun Metal for gun metal. Very fine grain, and spray very nicely to.
