My lumber supplier came to me to ask some advice. My supplier sent out a large slab top 2 3/4 thick to be finished that was clear coated and after sitting for a few days the finisher noticed saw dust on the floor under the top. Apparently something has gotten into the slab or was in the slab and is going to town boring away. The lumber supplier wants to put it into the kiln to kill the infestation. What will this do to the finish at 170 degrees? What options are there? This is a $5000 top.

From contributor B:
I am having a similar problem. I have a finished slab bench made of ambrosia maple with what appeared to be some termite holes near the end of the board. I assumed they were inactive as the slab sat in my shop for months before I turned it into its current form. It has been finished for about four months. Recently I started noticing tiny piles of ultra fine powder on top of the finish. After close (magnifying glass) inspection I can see a pinprick of a hole, 1/64th" or less that every few hours or so is letting out more dust. I do not have access to a kiln.
