Humbrol Enamel Paint ... is a solvent-based, fast-dry paint developed for use on plastic model kits, however it can also be used on other substrates such as ceramics, sealed wood and plaster, metal, glass and cardboard. Brush straight from the tin but dilute (2 parts paint to 1 part thinner) if used with an airbrush. Coverage is approximately 0.3 sq m per 14 ml tin. Although the drying times will vary based on the ambient air conditions, the gloss, matt and satin paints will be hard dry within a day. Recoating can usually be done after 6 hours. The metallics take a little longer to dry and should only be polished when completely dry. All enamel paints clean up with thinners.
