Vallejo 77.657 Metal Varnish Gloss (32 ml)
The varnish has been formulated especially for airbrushing; it dries very fast and does not leave fingerprints (“no tack”). Gloss Varnish 77.657 can be applied directly or diluted with distilled water or Thinner 71.261. In some cases, a layer of varnish is enough but if more layers are required, an interval of 30 minutes is suggested between each coat. Once protected by the varnish, the colors resist the application of oils, glazes, and even pure turpentine and light washes with alcohol.
