Engraving & Layout White is a unique low gloss, water based coating designed expressly for the metal worker. It is a non-glare coating that has excellent adhesion to brass, steel and plastic surfaces. It readily accepts pencil and ink layout lines and is completely erasable. If you need to correct a line, just erase with a non-abrasive eraser. After erasing, the line can be re-drawn without reapplication of Engraving & Layout White. When you are ready to remove Engraving & Layout White, just wipe the surface with a dilute ammonia and water solution or any window cleaner that contains ammonia. Engraving & Layout White contains no silica, so it will not dull gravers or other metal working tools.
