Acrylic Model Paint VALLEJO Model Air 17 ml — Dark Grey (RLM42) in Bottle

VALLEJO Model Air 17 ml — Dark Grey (RLM42) in Bottle is a water‑based acrylic paint formulated for airbrush and brush use on plastic, resin and metal model kits. This Dark Grey (RLM42) shade is part of the Model Air range, which reproduces historical military colours with attention to pigment quality and smooth flow. The paint is supplied in a 17 ml dropper bottle designed to minimize evaporation and allow precise dispensing for scale modelling, touch‑ups and layering.

Advantages

The fast‑drying, matt acrylic formula provides fine pigmentation and consistent coverage while preserving small surface details. Model Air flows smoothly through airbrushes at recommended low pressures and can be used directly or thinned with Vallejo Airbrush Thinner or Flow Improver for different spray characteristics. The water‑based, non‑flammable composition simplifies cleaning and reduces solvent exposure compared with traditional lacquer paints.

Suitable for

• Airbrushing scale models, aircraft and military miniatures
• Brush painting details, panels and touch‑ups on plastic or resin kits
• Painting metal parts and photo‑etched components with careful surface preparation

How to use

Prime the model surface before painting to ensure adhesion and uniform appearance. For airbrushing, use the paint directly or thin it with a compatible airbrush thinner or flow improver to achieve the desired viscosity; recommended compressor pressure is approximately 15–20 PSI (0.5–1 kg). Apply in several thin, even layers, allowing brief drying between coats to build colour without obscuring detail. For brush application, use thin layers and avoid excessive brushing that may lift underlying details. Clean the airbrush after use with an appropriate cleaner to prevent clogging.

Usage recommendations

Observe standard workshop safety and follow the product’s safety data sheet. Although water‑based and non‑flammable, work in a ventilated area and allow full drying before handling or assembly. Store the bottle capped and upright at moderate temperatures to preserve the paint.
