2-14-13.  I'm giving this 5-stars on initial review.  We shall see over time how well it works.  Product is a very liquid black silicate adhesive. Use care when applying as it tends to be runny and drips. If you spill it one anything, as I did on the nice fireplace carpet, it cleans up easily with soap and warm water when still wet. I actually used Mr. Clean multi-surface cleaner and it worked well to remove the black adhesive from a colored carpet onto which the glue dripped. It comes off your hands easily. So far, it's good.
