FP-923 is used for the detection of fine cracks, porosity, and through leaks on metals, composites, synthetic materials, and some plastics. The materials used are low in sulfur and halogens, VOC free, and safe for use on all metal surfaces. It is bright yellow, smooth washing and non-gel forming, allowing a clean wash cleanly from rough surface. It is applied by immersion, spray, or wipe on and is approved for high sensitivity aerospace applications.

For Method C applications it is used with E-59, E-59A, R-503, and R-504.
