Anyone try Dynamat, HushMat or others?

I used Hushmat. I bought it from a friend who can buy it wholesale. Look for deals, they are out there. Two boxes got the job done.


How is sound reducing "before" and "after"? Or do you have a good "before" to judge from?

Was that two of these boxes/kits: BLACK, 20 SHEETS -- 12.1 x 23 in.; 39 sq. ft. I see them on Amazon for $150 each.

How does Fat Mat compare: [ame="http://www.amazon.com/Rattle-Trap-FatMat-Install-Included/dp/B003TUNRGM/ref=cm_cr_pr_product_top"]50 Sq Ft Rattle Trap FatMat 80 mil Bulk Pack Install Kit Included : Amazon.com : Automotive[/ame] It's $93 for 50sq ft.
