I would agree with using Ted. Great guy and very prompt.
Green Glue is an excellent product. There are other things out there but nothing that has proven to be as effective.
Like an wise man once posted about this topic:
"You can put peanut butter between drywall sheets and it will do something. We just don't know what, how much, where, and what is good vs bad."
With Green Glue, you know all of the above.
