This thread got me enthused. After doing some research, I came across that same link (sounddeadenershowdown) which all made sense to me. I decided to do it once, and as best as I could.
So what I wanted was a bit of sound deadener just to control panel vibrations. I bought a Dynamat xtreme bulk pack from ebay. $186. I used it quite sparingly, and I think I bought way too much.
I didn't want to spend too much on a roller to apply the Dynamat, so I bought a metal caster wheel from Bunnings for a $3.
For the sound barrier I bought a roll of Sonic Bar Mass Loaded Vinyl (MLV) from ebay. $215 with freight for 7 square metres. It is heavy stuff, 4kg per square metre. I think it is the right quantity.
To separate the MLV from the car metal I bought a heap of camping mats from KMart. They are EVA, a type of Closed Cell Foam (CCF) and 5mm thick, and only cost $5 each mat.
I used double sided tape from Aldi to stick the CCF to the MLV (just to keep the CCF from falling off really). It was heavy duty and supposedly good up to +90 celcius. There are probably some glues out there that would have worked fine, I just got overloaded with the variety at Bunnings, and the double sided tape was easy.
To stick the MLV to the Car metal I used 3M Dual Lock SJ3550 again from ebay. It is a kind of industrial velcro, and I will just call it that but it is a bit different. It is strong stuff, and is able to support the heavy MLV over a range of temperatures (hopefully). It is a bit pricey, about $13 per metre strip, and the distance it actually covers is halved due to sticking both sides.
So I removed the trim, then put extra Dynamat where I could see larger bare panels with no factory deadener.
Then I cut the MLV to size (leaving holes for trim holes etc), stuck the velcro on here and there (I probably used too much) on the MLV, and in the same spot on the car body. Then I cut the CCF to the same shape but cutting extra holes through where the velcro will attach, then sticking the CCF to the MLV using the dual sided tape. Then attach the velcro and it is done. If I need to remove it later to get at wires or the panel it is easy to just separate the velcro and pull it off.
So far have done the two rear wheel arches and the cargo bay, as well as the wagon rear door. As well as the passenger side front floor (just plain MLV layed under the carpet, didn't think it needed CCF or velcro sticking down). I put wiring through the wagon rear door and through the rubber hose thing, then all the way to the front while I was at it (for a rear view camera install I have planned for later). The trim removal is a real pain. Also the MLV is heavy, so it is hard to hold it up to cut to size (especially for the rear wagon door). The whole thing probably took 3 full days.
So I still have the 4 doors to go. If I have any MLV left over (I think it will be getting tight) I will do underneath the driver carpet.
