RAL 7048 Pearl Mouse Grey

RAL 7048 Pearl Mouse Grey: a grey that comes alive in the light

Pearl Mouse Grey is the pearlescent version of a mid grey, part of the RAL range of effect shades. Fine pearl pigment gives it a soft shimmer that changes with viewing angle, turning an everyday grey into something more refined. It is used in architecture, design and bespoke vehicle finishes. For modelers it is a great option for modern cars and bikes, custom builds and display pieces, where a grey with subtle movement looks far richer than a flat solid.

The problem with pearls

Pearl effects show every mistake: wet passes cluster the pearl into blotches, and uneven coats change the colour from panel to panel. Controlled, even, slightly drier passes give a smooth, consistent shimmer.

How to apply

1. Shake the bottle for at least 60 seconds.
2. Prime with a grey primer and let it dry fully.
3. Airbrush straight from the bottle, no thinning needed. Use a 0.2–0.4 mm nozzle at around 20 PSI (1.4 bar) and apply light, cross-hatched coats, letting each one flash off before the next.
4. Keep the airbrush moving at a constant distance for an even effect.
5. Let the paint cure overnight before masking or clear-coating.
6. Seal with a water-based clear coat: gloss for a factory shine, or satin or matte for work vehicles and interiors.
7. Clean the airbrush with water before the paint dries.

Why modelers choose Koloi Aqua

• Ready to spray: no guessing thinning ratios, the same result from every bottle
• Cleans up with water, so there are no strong solvent fumes at the bench
• Fine pigment grind for 1:8 to 1:72 scales, so panel lines and detail stay crisp
• One system: primer, colour and clear designed to work together

Shelf life

Estimated shelf life of more than 12 months when stored tightly closed between +10 °C and +28 °C, away from frost and direct sunlight. Shake well before use; if the paint has thickened or separated and does not remix, do not use it.
