Vallejo Mecha Color 69.012 Purple A bottle of Vallejo water-based Mecha Color acrylic paint, supplied in a 17ml dropper bottle. Mecha Color is a range of acrylic airbrush colors, designed by Vallejo especially for painting robots, Gundam, Transformer and Gunplas figures. The innovative formulation of the colors, although water-based, guarantees a maximum resistance to manipulation, impacts, friction, scratches and overall extreme wear. Once dry, the color appears the same as the injected plastic color, respecting all the details of the kit. Note that it is airbrush ready, and although it can be thinned, where possible it is better to vary your spraying pressure and distance to get the correct application, as this has been found to get a stronger, more durable finish. For maximum durability, prime with Mecha Color primer, leave to fully cure for 48 hours, then apply paint and leave to cure for another 48 hours before applying Mecha Color varnish and leaving another 48 hours before handling.
