Blue Layout Stain

Bearing Blue
Bearing blue is most commonly used for balancing & blueprinting engine components for precise clearances.
Bearing blue leaves a distinct blue mark on components that require machining for a perfectly balance engine. Spreads easily, will not clog or dry out. Use freely as required to locate “high spots” or scratches during fitting and scraping operations. Made in Australia.

Oil based paste for indicating high spots on machine bearings, machine tool beds etc. Easily removable with methylated spirit.

When Engineer's blue is mixed with methylated spirits it forms a quick drying stain which is known as marking blue or layout dye.
