How do I paint metallic effects without an airbrush?

To paint metallic effects without an airbrush in scale modelling, follow these steps:

1. Use High-Quality Metallic Paints
   Opt for brands like Vallejo Metal Color or AK Interactive. These provide a smooth finish even with a brush.

2. Thin Your Paints
   Metallics can be thick and grainy, so thin them slightly with water or a compatible thinner. This helps avoid brush strokes.

3. Apply in Thin Layers
   Build up opacity gradually with multiple thin coats rather than one thick layer.

4. Use a Soft Brush
   A high-quality synthetic or sable brush helps achieve a smooth application and minimises streaks.

5. Dry Brushing for Highlights
   Lightly load a dry brush with metallic paint and gently sweep it over raised details to create a realistic sheen.

6. Blending and Feathering
   Use a damp brush to soften edges between light and dark metallic areas for a smoother gradient.

7. Gloss or Satin Undercoat
   A black gloss undercoat enhances the metallic shine and depth, especially for silver and chrome finishes.

8. Polishing for Extra Shine
   Once dry, gently buff the surface with a soft cloth or cotton bud to bring out the shine.

9. Weathering and Washes
   To add realism, use dark washes to shade recesses and edge highlights to emphasise details.

10. Sealing Your Work
    Use a gloss or satin varnish to protect the metallic finish and maintain the shine.
