Gold Acrylic Brush Paint

This is the simplest, cheapest way to get a metal appearance on plastic.  Unfortunately, it also gives a very unrealistic result, and most people are not pleased with its appearance.  If you're keen on using a paint brush, I recommend an enamel like Testors.

Pros                                Cons
· Cheap                         · Looks particularly crappy
· Easy                            · See #1

Synopsis:
Use only to touch up small areas.  Even then, use enamels.  In other words, avoid like the plague.  This stuff goes on grainy and streaky.
