Tamiya XF-25 Light Sea Grey vs Other Grey Acrylics: Best for Aircraft Models

Choosing the right grey acrylic for your aircraft model can be the difference between a convincing scale finish and a toy-like appearance. Among the most popular options is Tamiya XF-25 Light Sea Grey, a versatile shade used on everything from WWII naval aircraft to modern jets. But how does it stack up against other grey acrylics from AK Interactive, Vallejo, and Mr. Hobby? In this comparison, we'll break down the color, finish, and application differences so you can make an informed decision for your next build.

Whether you're painting a Zero or an F-16, the grey you choose affects not only realism but also how panel lines and weathering stand out. We'll look at Tamiya's offering alongside alternatives like AK Interactive's Gen-3 line, with a focus on practical results for aircraft modelers.

Tamiya XF-25 Light Sea Grey: A Closer Look

Tamiya XF-25 Light Sea Grey is a flat acrylic formulated for brush and airbrush use. It dries to a matte finish that closely mimics the appearance of worn military paint. The color itself is a light, slightly greenish-grey that was historically used on many Japanese and US Navy aircraft. It's also a favorite for modern aircraft undersides and radomes. When thinned with Tamiya X-20A or isopropyl alcohol, it sprays smoothly and covers well in two to three thin coats.

One of the main advantages of XF-25 is its consistency. Tamiya's acrylics are known for their fine pigment grind and reliable adhesion to plastic. The paint also tolerates masking tape well, making it ideal for complex camo patterns. However, some modelers find the color slightly too green for certain modern schemes, which is where alternatives come in.

• Finish: Flat matte, ideal for scale realism
• Coverage: Opaque in 2-3 thin coats when airbrushed
• Best for: Japanese naval aircraft, US Navy WWII planes, modern jet undersides

AK Interactive Gen-3 Grey-Blue: A Cooler Alternative

For those who find XF-25 too warm, AK Interactive's Gen-3 range offers a more neutral option. AK11165 Gen-3 Grey-Blue 17ml is a popular choice for modern NATO and US aircraft. It has a subtle blue tint that reads as a true neutral grey under most lighting. The Gen-3 formula is designed for both brush and airbrush, with a self-leveling property that reduces visible brush strokes. This makes it a strong contender for modelers who prefer hand-painting smaller details.

When compared side by side, AK11165 appears cooler and slightly darker than XF-25. It's an excellent choice for F-16, F/A-18, and Eurofighter schemes. The paint also dries to a satin finish, which some modelers prefer as a base for decals and washes. If you're building a modern jet and want a more accurate grey, this AK shade is worth considering.

• Finish: Satin, good for decal adhesion
• Coverage: Excellent, one coat often sufficient for base color
• Best for: Modern NATO, US, and European jets

Comparison: XF-25 vs AK11165 and Other Greys

To help you decide, here's a quick comparison of key characteristics. Tamiya XF-25 Light Sea Grey is warmer and greener, while AK11165 Gen-3 Grey-Blue is cooler and slightly darker. For a pure neutral grey, many modelers turn to Mr. Hobby H-305 or Vallejo Model Air 71.044. Each has its own drying time and thinning ratio. Tamiya's acrylics are alcohol-based, so they dry faster and are more durable once cured. AK's Gen-3 is water-based and more forgiving for brushwork.

Another factor is availability. Tamiya XF-25 is widely stocked and often comes in larger bottles. AK Interactive's Gen-3 is available in 17ml jars, which are convenient for small projects. If you're looking for a versatile grey that works for both WWII and modern subjects, XF-25 is a safe bet. For a more accurate modern jet grey, AK11165 is the better choice.

• Tamiya XF-25: Warm, greenish-grey, matte finish, fast drying
• AK11165 Gen-3 Grey-Blue: Cool, neutral grey, satin finish, brush-friendly
• Vallejo Model Air 71.044: Neutral grey, pre-thinned for airbrush

Application Tips for Aircraft Grey Acrylics

Regardless of which grey you choose, proper surface preparation is key. Always prime your model with a fine primer to ensure even paint adhesion and color consistency. For Tamiya XF-25, thin with Tamiya X-20A or isopropyl alcohol at a 1:1 ratio for airbrushing. For AK11165 Gen-3 Grey-Blue, use AK's own thinner or distilled water. Spray at 15-20 PSI with a 0.3mm or 0.4mm nozzle for best results.

When painting large areas like wings or fuselage halves, apply thin coats and allow each to dry before the next. This prevents pooling and ensures a smooth finish. After painting, seal with a clear gloss coat before applying decals, then finish with a flat coat for a realistic look.

• Always prime before painting grey acrylics for consistent color
• Thin Tamiya acrylics with alcohol; AK Gen-3 with water or dedicated thinner
• Apply 2-3 thin coats for best opacity and smoothness

Both Tamiya XF-25 Light Sea Grey and AK11165 Gen-3 Grey-Blue are excellent choices for aircraft modelers, but they serve different needs. If you're working on a WWII or early jet subject, XF-25 is a reliable, time-tested option. For modern jets requiring a cooler, more neutral grey, AK11165 is the better match. Whichever you pick, you'll find both at Panda Hobby to elevate your next build.
