Shot Peening improves metal and weldment resistance to fatigue, stress corrosion cracking and galling. To provide this benefit, it is important that shot peen coverage be uniform and complete. A liquid tracer (Fluoro-Finder III) provides a coating which is removed at a rate proportional to peening coverage, providing visual feedback on the uniformity and completeness of peening coverage. Fluoro-Finder III, has a pigment which fluoresces under ultraviolet light making the determination of the degree or percentage of coverage quick, easy and foolproof. Use of this tracer eliminates the need for 200-percent coverage in order to be assured of complete peening.
