Winsor & Newton Professional Retouching Varnish

For protecting a recently finished oil, alkyd or acrylic painting, Retouching Gloss Varnish offers an ideal, non-yellowing temporary solution. Because most paintings take months to dry completely, Retouching Gloss Varnish can be applied on touch-dry paint, to allow the inner layers to dry completely while protecting the surface from dirt and impurities. It dries in only a few hours and is available in a handy 14 oz. aerosol spray can.
