A bottle from Vallejo's auxiliary series. The auxiliary series consists of a number of auxiliaries such as mediums, varnishes and thinners. These can be used to influence color properties such as gloss, transparency or drying time. They are highly resistant, can be applied by brush or airbrush and dry very quickly. They are applied as a final protective layer and can also be mixed with the paints to change their gloss properties. The range is diverse: from glossy to ultra-matte.
Metallic Medium gives colors a pearlescent finish.
