    I use the 3 can system when inspecting nuclear parts and they are widely used in all other industries.
    I have the PCN level 2 qualifications to use these and interpret the results.
    They are excellent at revealing "Surface Breaking" defects and by this i mean a crack or fissure has to be present to allow the penetrant to penetrate
    Into it.
    Thats why we use magnaflux for detecting any "slight sub surface" defects and then ultrasonic techniques for anything deeper than slight sub surface.
    I inspect equipment using all 3 techniques and the defect that always ends up with items being scrapped or major repairs is the surface breaking variety, as this is how cracks propagate. Buried defects can be left for years as long as they are not planar (crack like)
    Just remember to follow the instructions and dont clean the dye off using the spray directly as it washes the dye out of any small cracks/fissures. Spray the cleaner onto a rag and wipe off.
