Tamiya XF-91 IJN Gray (Yokosuka Arsenal)

Tamiya XF-91 IJN Gray (Yokosuka Arsenal) 10 ml – matt acrylic paint for model kits

Tamiya XF-91 IJN Gray (Yokosuka Arsenal) 10 ml recreates the specific grey used on Imperial Japanese Navy ships painted at the Yokosuka Arsenal: a medium grey with a neutral to slightly cool hue, matt finish, and very well suited to hulls and superstructures.

Designed for IJN destroyers, cruisers and battleships in the Yokosuka scheme, it works as an excellent base for subtle modulation, salt streaks, rust and maintenance runoff effects.

The reference Tamiya XF-91 IJN Gray (Yokosuka Arsenal) 10 ml belongs to the XF series (matt finish) designed for scale modelling on styrene plastic, resin and wood; its controlled viscosity promotes smooth self-levelling and even coverage while preserving rivets, panel lines and fine details, and allows you to work in thin layers with both brush and airbrush, with drying times suitable for masking and applying decals safely.

Use on models and common scales

In naval scales 1/700–1/350 it is ideal as a base colour for hulls, superstructures and masts of IJN ships in the Yokosuka scheme, making black/brown washes, rust and waterline marks easier to apply; at 1/200 and larger scales it maintains a clean read on barbettes, turrets, davits and deck equipment; in harbour dioramas at 1/700–1/350 it works well on cranes, fenders, buoys and dockside buildings, blending with pigments and salt effects for a realistic, in-service finish.

Thinning, airbrushing and brushwork

For airbrushing, start with a 1:1 ratio with Tamiya X-20A and adjust according to nozzle size and pressure (approx. 12–18 PSI), applying short passes to avoid build-up in panel lines; for brushwork, apply without overworking the area and, if you wish, add a small amount of retarder to improve levelling; between coats, allow the solvents to evaporate to protect the surface detail of the model.

Surface preparation and priming

To get the best performance from Tamiya XF-91 IJN Gray (Yokosuka Arsenal) 10 ml you need a proper base: wash the parts to remove mould release agents, dry-fit, clean up joints and apply an even primer; white primer increases perceived brightness, while grey primer provides a neutral, controlled base; a light micro-sanding afterwards improves adhesion and smoothness.

Finishes, varnishes and compatibility

Once Tamiya XF-91 IJN Gray (Yokosuka Arsenal) 10 ml has fully cured, you can seal it with varnish depending on the final result you want: matt to preserve its tactical character, satin to help blend decals, or gloss before decal application; explore our range of paints and varnishes for model kits to choose the best option; after varnishing, apply washes, panel lining and weathering effects, allowing for proper curing times to avoid lifting the paint.

Practical modelling tips

• Thin, successive coats: prioritise several light passes to avoid losing fine detail.
• Safe masking: use quality masking tape, seal the edges with a cotton swab and peel it back diagonally once the paint is touch-dry.
• Test first: fine-tune viscosity, pressure and distance on a spare piece before moving to the actual model.
• Full curing: let the paint fully cure before handling, adding decals or applying effects.
