Translucent weathering liquid does not obscure surfaces like paint, surfaces are clearly are visible through the dried dirt stain. This makes weathering more realistic because most real dirt does not obscure surfaces. Makes clean models look dirt stained with just one coat. All dirty colours are made from water soluble dyes and can be wiped and smudged with a damp cotton bud even after being dry for months. Fill panel lines by applying a fine coat, (allow to dry), and then wiping the surface residue away from the flat surfaces using a damp cotton bud leaving the rest trapped in the panel lines. The more applied, the darker the colour gets. Made from dyes, not pigments; dyes dissolve into liquids which helps create finer weathering effects. Not visible on black surfaces. Seal with a mist coat of matt varnish spray. Available in two sizes, 18ml and 50ml.
