Hello, I have read your posts regarding the noise reduction using Don Sambrook's product. I used his email address to try contacting him 2 times in the last 6 months, but have not gotten a response. Do you know if he is still selling this material? Do you have any other contact info for Don other than the email address on his website? Any help would be greatly appreciated. Best regards, Ken Frisbie 440.812.3349
