I am going to test a poultice on Tuesday, I just wanted to send these pics
to see if someone has a thought as to what this could be.  If you look
closely at the picture from underneath you can see a faint dark line there
too.  In person you can see it better.  So this couldn't be a caulk issue
right?  Its only on that edge and obviously there is no caulk there.
Thoughts?
