Provides maximum sensitivity and defect exposureExcellent colour contrast
Very fast drying
Outstanding wetting properties

Directions for Use:
Shake can well before use. Spray thinly and evenly onto the component, using just enough to wet the surface and allow to dry for about 10 minutes to a thin, white coating. Excessively thick coatings will tend to mask defects. Cracks appear as red lines and porosity as spots. A pink film indicates incomplete removal of the Penetrant.
