Ach,… Sorry.
It appears that perhaps I am using a term too esoteric even for the members of this community, or we have internally been using a term incorrectly.
We consider haloing to be when coating leaks into an unsealed connector body such that when you look down into the connector, coating has wet the molding around a connector pin socket, but not transferred to the metal contact . Hence you get a ring of fluorescence at that location. Often defected by some customers but we call it a process indicator. This same concept can be used on other non-circular artifacts also.
I think the term was used by a large defense customer of ours and we have more or less adopted it internally.

Rich, can you expand on what you mean by haloing? Like fish eyes? Or Dewetting?

If anyone has any image of coating "haloing " within a connector, header or like I would appreciate getting that image(s).
