Herschell Engineers Marking Blue 300ml

Herschell Engineers Marking Blue 300ml (HERS0055/HERS0030) is a high-precision layout fluid used by machinists, toolmakers, and fabricators to coat metal surfaces before scribing. It provides a dark, high-contrast matte finish that makes etched lines stand out clearly, ensuring accuracy during cutting or drilling.

Key Features

• High Contrast: Dries to a vibrant, non-glare blue film that makes even the finest scriber marks highly visible.
• Fast Drying: Typically touch-dry within 30 to 60 seconds, allowing you to start your layout almost immediately.
• Non-Flaking: The formula adheres tightly to polished or rough metal surfaces and won't flake or crack when you scribe through it.
• Easy Removal: Can be wiped away instantly using a cloth dampened with methylated spirits or a petroleum-based solvent once the job is done.
• Aerosol Convenience: The spray format ensures an even, thin coat without the brush marks or "pooling" often associated with traditional paste or liquid-and-brush versions.
