Was wondering what techniques can be used to simulate brass on a plastic casting. For example, I'm working on a few WW1 softskin vehicles with plastic parts and would like to paint realistic radiators, headlamps, and hubcaps.
One of the best metallic paints I've used are the Citadel acrylics, sold for figure painters of fantasy games. They have names like "Skull white", "Chaos Black" and "Bleached bone" but they're very good, can be brush painted or airbrushed and have great covering properties. Visit a nearby gaming shop and take a look to the racks, probably there must be several brass shades in there. D.
