This formula acrylic colours with a satin finish, extra resistant and impact proof especially designed for airbrushing surfaces exposed to aggressive manipulation. The advanced formulation contains a revolutionary component which guarantees exceptional adherence on even the most difficult surfaces, and offers great resistance to rough handling, impact, friction, scratches, etc. Once dry, the Mecha surface looks the same as the original plastic of the model, while yet the smallest details of the original remain clearly visible. The colour range includes primers as well as special varnishes - also with an exclusive formulation- and a series of colours for aging and weathering effects. It is recommended to apply the Mecha colours in several layers on the previously primed surface; a few hours after application the colours will have dried to form a homogenous coating of extraordinary strength and resistance. Mecha Colour can be airbrushed directly or diluted with Vallejo Airbrush Thinner or Flow Improver, and the colours can also be applied by brush. The compressor adjustment recommended is 15 - 20 PSI o 0.5 to 1 kg. For best airbrush maintenance we recommend using the Vallejo Airbrush Cleaner. Mecha Colour is not flammable, and does not contain solvents. Fast drying, exceptional adhesion on all type of plastics.Great resistance to impacts and scratches 24 hours after application.Use direct from the bottle or dilute with Vallejo Airbrush Thinner.Shake well and apply with a brush or airbrush in thin layers.
