A material supplied in wet or dry form to be applied to the part being penetrant inspected, after the excess surface penetrant has been removed. The "wet" developer, on drying, provides an absorbent white background to the part for maximum color contrast, and enhances the bleed out of the penetrant from the cavity to obtain increased inspection accuracy.
