NDT!

Zyglo� is the brand name of a dye-penetrant inspection process.  The
process consist on dipping the suspect part into a water or solvent
soluble(sp) fluorecent dye.  Remove the part, allow it to "dwell", or
sit there, and absorb the dye. Rinse the excess dye off and apply a
"developer" which gives the part a uniform color.  Examine the part with
a blacklight looking for places the dye has seeped into any
"discontinuities", or cracks.

Google "dye penetrant inspection" and I'm sure that you'll turn up
hundreds of site detailing the process *much* better than I.
