I went for Dynamat for both my EK wagon and daughter's EK ute. Its not cheap, but it sticks like dog poo to an army blanket. What worried me with the cheaper brands is the risk of them coming unstuck. No big deal on the floors, but the roof sits in full sun. If the roof comes unglued, you have to remove the hoodlining. To remove the hoodlining, you are likely to have to remove the front screen. I ain’t touching that screen again.
The metal surfaces were hit with rust killer (deoxidine), then two coats of black epoxy, brushed on.
I bought the large size Dynamat sheets (18”x32”). The wagon floor took 11 sheets (I did not do the cargo area). The ute floor took 6 sheets. The wagon roof took 9 sheets. The ute roof took 3 sheets. The cut edges of Dynamat are sharp. I used Dynatape to seal them in (3/4 roll per vehicle). No big drama if they are under the carpet, but it would be just my luck to lift the carpet to work on something and slice myself open. Bunnings sells aluminium duct tape that would do the same job.
Put the sheets out in the sun before fitting - it softens the mastic, making them easier to bend. Buy a fancy little roller from Bunnings to roll the material into all the crevices. Poke a podgy up from under the car to mark the bolt holes in the floorpan, then run a stanley knife around the podgy tip to cut out a circle of dynamat. Do not just poke holes and drive the bolts through the dynamat... the black mastic is a bugger on threads.
Cheers,

Is there a noticeable difference in the level of sound with the use of Dynomat?
