Thank you so much for the refund. It is very gratifying to deal with honorable company that delivers on its promises. It is incredible how few such companies seem to exist.

 Don’t know what the black spots are. From checking on Google on fungus they seem to look just like a fungus. I am having a termite/ moisture inspection for the sale of my home. It is scheduled for 9/10. Let’s see what the inspector has to say.  I will let you know.

 Thanks for your followup.  William E.
