Hi Graham, the sound deadener I used was just a generic one I brought from Allcar Carpets here in Melbourne who I will be getting to make my carpet sets. It cost around $200 to do the entire floor, including the rear seat panel. It is very user friendly as is soft/plyable and can be pushed into all the different contours and shapes on floor pan, I might even put some inside doors and rear 1/4's. I have also used a brand called "DEDNA" and Tru Fit Carpets in Dandenong advertise a similar product in street machine, but haven't used their product. I would suggest trying to find source some at your local motor trimmer as it may be a bit pricey to have sent to Qld due to weight, or check out www.trufitcarpets.com.au. Hope this helps paul.
