A composition containing ferromagnetic particles colored for contrast or of a quality to fluoresce under black light either in the form of (1) a dry powder for dry inspection method which may be dispensed from a squeeze container, or (2) a dry concentrate for suspension in a light petroleum oil or water bath for wet inspection method, or (3) a prepared light petroleum oil base mixture which may be dispensed from an aerosol container. The ferrous particles accumulate by magnetic attraction at any surface flaws (cracks), thereby permitting the flaws to be readily discernible.
