Product Description GW-1 Fluorescent Magnetic Powder is a dry concentrate, mixed with light oil or water to find microscopic cracks in ferrous metals by the magnetic particles method. Glo-netic GW-1 can be used for inspecting critical parts. The particles respond to magnetic leakage fields created by cracks and other flaws. They rapidly collect at such fields and when viewed under black light, they reveal and profile flaws as bright, glowing yellow-green marks.
