Vallejo Primer 70630 Steel Grey Primer (18 ml)

Vallejo Surface Primer 70630 Steel Gray (18 ml) is a primer from the Vallejo Surface Primer line in the shade of steel gray. The primer creates a thin, well-adhering layer that prepares the surface for subsequent painting without obscuring the model’s fine details.

Neutral primers are suitable as universal bases: white enhances light and rich shades, gray is a safe compromise, and black aids in shading, metal effects, and dark camouflage.

Shake the bottle thoroughly before use. The model should be clean, dry, and degreased. It is better to apply the primer in several thin layers rather than a single thick layer. When airbrushing, start with lower pressure and adjust the distance, pressure, and thinning as needed based on how the paint behaves. Allow the surface to dry thoroughly between layers.
