GE Clear Silicone Glue is NOT AN INSULATOR.
While trying to assure that my speaker was secure, I used GE Clear Silicone Glue around the edges of the speaker. I managed to touch the speaker terminals with the glue--thereby creating a short to ground. I verified this with my conductivity meter.
If you are considering using this product, keep it away from electrical connections. It may eventually become an insulator-- after it has had a very long time to cure.
