LA-CO (Elk Grove Village, IL) recently developed the PRO-LINE WP, an industrial grade liquid paint marker that is designed for use with wet surfaces. Engineered with a permanent, fast-drying and low V.O.C. formula, Markal PRO-LINE WP liquid paint markers are designed to resist spreading when in contact with water or water-based liquids, while also meeting low V.O.C. regulations. This formula makes the PRO-LINE WP line ideal for a wide range of applications across an array of industries, such as those most common to the automotive industry at manufacturing and design plants.
