Markal Valve Action Metal Marker Valve Action is a fast-drying liquid paint marker that provides long-lasting wear- and weather-resistant marks and is engineered to contain low levels of chlorides, halogens, low melting point metals, and sulphur. The low corrosion paint formula is safe for use on stainless steel, alloys and other superalloy metals and will not contribute to unwanted corrosion, degradation, or pitting from use.
