Price??? I cannot remember except to say you are correct. The cost does hurt but I did it anyway. There is no real way to cheap out on this process except for selective application and careful use. These materials are used in sound control applications which is a special market with limited competition and a high barrier to developing the science, product development, marketing and limited market thus high prices. Sounds like the parmaceutical sector!!! EAR is the product used. Comment: Use extreme care to assure the product is affixed soundly to the firewall and chassis. Also make every effort to cover all the areas you intend to cover. Noise leaks through holes, cracks etc. Seal the material edges with aluminum tape for sound and air barrier. You must buy the material in sheets which are about 2x4 feet. Bob Smiley N94RJ
