RAL 7031 Blue grey - 400ml

🚗 Colour accuracy sells builds. RAL 7031 Blue grey - 400ml reproduces the real-world tone with the pigment density and coverage scale modelers rely on for a factory-fresh result, first coat to last.

RAL Classic is the colour-matching standard created in Germany in 1927 to give industry a single, unambiguous colour reference independent of brand or manufacturer. It remains the default specification for commercial vehicles, machinery, road signage and military equipment across Europe, which is why so many real-world trucks, tractors, trailers and armoured vehicles carry an official RAL code rather than a manufacturer-specific paint name. In the RAL Classic range, RAL 7031 Blue grey falls within the grey tones, the largest RAL family, standard across industrial equipment, vehicle chassis and machinery.

RAL 7031 Blue grey is an aerosol spray paint that is supplied ready-to-use in a pressurised can, formulated for even coverage across larger surfaces. It suits 1:8, 1:10 and 1:12 R/C bodies and larger static models, as well as full-size hobby and DIY respray work where a fine airbrush cartridge would run out too quickly.

💡 Laboratory Application Tips

• Preparation (Primer): A neutral Grey Primer is recommended as a safe, all-purpose base that preserves the true tone and opacity of this colour without biasing it warmer or cooler.
• Painting Technique: Shake the can thoroughly for at least a minute, then spray in light, even passes from roughly 20-30cm, keeping the can moving to avoid pooling. Several thin coats give better coverage and a smoother finish than one heavy pass.
• Finishing: Allow full curing time between coats and before clearcoating; aerosol lacquers can stay workable for longer than airbrushed paint, so patience at this stage avoids solvent wrinkling later.

⚠️ Chromatic Fidelity Notes

Real Scale vs. Miniature: This formula is adjusted to counter the "scale effect," so light reflection on the miniature stays proportional to the real vehicle or object rather than looking artificially pale or dark.

Visual note: Product photos are for reference only. The full three-dimensional depth and true pigment brilliance only become visible once the model is painted and properly clearcoated.
