Tamiya Acrylic Paint Mini XF-21 Sky

Tamiya XF-21 Sky is the pale green-grey "Sky" worn on the undersides of RAF aircraft — the classic Battle of Britain-era underside tone. Essential for accurate British WWII fighters and bombers.

Best for

• RAF aircraft undersides
• Battle of Britain-era schemes
• Brushing or airbrushing once thinned

The authentic RAF underside ‘Sky’. Sprays smoothest thinned with Tamiya X-20A — a natural pairing.
