This paint can be polished giving a much better metallic effect. It can be applied with brush or airbrush. When used with brush always paint in the same direction.
Different interesting effects can be obtained depending on how strongly the paint is polished. Use different polishing techniques for different effects.
For example, no polishing will result in a matt effect, while gentle polishing, or more strong polishing will result in a more highly burnished effect. To finish apply a varnish with airbrush or spray to prevent oxidation and result in a durable finish.
