Airbrush and Brush Use Tips

Whether you brush or airbrush, Tamiya X-21 blends smoothly with other acrylics and helps reduce sheen. For airbrushing, use Tamiya thinners such as 81020, 81030, 81040, 81520, or 87077 for best atomisation and flow.

Surface Compatibility and Uses

Use this flat base with a wide range of modelling projects from kits to custom sculpts; its water-base formula makes cleanup straightforward and reduces surface tension on most hobby plastics.
