Tamiya 74532 - Spray Work HG Air Brush III double-action airbrush for scale RC model painting  [74532]

Spray Work HG Air Brush III

The Tamiya 74532 Spray Work HG Air Brush III is a double-action airbrush designed specifically for scale RC model painting. As an accessory for RC-scale finishing, it connects with Spray-Works compressors and Tamiya air cans to form a compact supply setup suited to bodywork, trim detailing, and small-part finishing on RC models.

Double-action control separates airflow and paint feed, giving the operator finer metering for techniques such as shading, gradation and gloss coats. The unit’s 0.3mm nozzle allows lines under 1mm when used with appropriate masking and steady hand techniques, which helps when painting panel lines, thin stripes and fine decals on scale bodies.

Ergonomics were addressed with a redesigned trigger for more comfortable, consistent control during longer sessions. The airbrush accepts Tamiya acrylics, enamels and lacquers when reduced and filtered per paint manufacturer guidance. Regular flushing between paint types is recommended to preserve nozzle performance and avoid clogging.

For RC modellers focused on body finishing and fine-detail paintwork, the Tamiya 74532 Air Brush III provides the control needed for thin lines and gradual shading while integrating into Spray-Works supply systems; maintain regular cleaning to keep nozzle performance consistent.
