Re: Dynamat/ sound proofing
I used 50 mil FATMAT but it's probably the same as zillamat. 65 sq ft did floors, firewall, behind the tank and under the headliner. Still need to do the doors, but the 130 sq ft bulk pack was $129.00 vs $1200.00 for Dynamat and I have enough left to do a double layer on the firewall, doors and floor.
