Cute Inge, but you have not answered the why or why not.  In all your 
years of experience, have you ever found a case of moisture ingress from 
the edges of a board, or from a board cutout area, which was not coated? I 
have yet to find one.

OK, the conformal coat question of the day:

Do you conformally coat the edges of a printed circuit assembly?  Why or
why not?

OK, that is two questions, or perhaps a half fractional question.....
