Sound Dampening Material Source

by Kevin Rhodes

Thought I would pass on a tip from the Volvo list. Someone posted that McMaster-Carr (www.mcmaster.com) had a sound dampening product that was the same as Dynomat for 20% of the cost of Dynomat. I ordered a couple sheets and can confirm that it is EXACTLY the same product as Dynomat, just without Dynomat logos printed on it. Cost is ~$12/sheet versus ~$80 sheet for Dynomat. On the McMaster website, search for acoustical insulation, it is the high temperature mastic on the first page.
