Thanks, everyone.
@Jedimerc: The paint is Semi-Gloss back and comes from Tamiya's line of model paints; I feel that the semi-goss finish gives a decent metallic look. The paint is designed for plastic models so it works fine for figures as well. The thing is, it will only provide even coverage if it's applied by airbrush. Brush painting large areas of vinyl with this paint just won't work. As for the wire, it's annealed florist's wire that I found at a craft store. It's a very rigid, almost springy wire that I believe is made for use by florists to create flower arrangements.
Cheers.
