Get it from: Freeway in Dandenong, Stylyn/Central Car Radio in Moorabbin (I can't spell that place), and Autobarn can order it if they don't have instore..those places should be able to install too.. or eBay if you want to source it
Doors: Deaden the outer door skin, place a diffuser directly behind the speaker, cover service holes with 3mm (doesn't need to be too thick) MDF, held with duct tape. then deaden the inner door skin.
Boot: boot lid, insides of the boot, as far as you can reach.
Number plate: behind it to stop rattling.
Doing a full on job probably need about two bulk packs. I only needed a door kit in my old 33, as I did the front half of the doors (inner and outer) only.

make sure your rear seatbelts are clipped in. They vibrate against your rear side panels.

u mean like apply it behind the number plate? Will the dynamat's adhesive wear off during wet weather or extremely hot summers?

yes it can fall off if not installed properly.

theres an excellent DIY guide to sound deadening on CAA, if you'd like the link.
Its got photos, and about 3 pages of forum discussion on it covering all the newbie questions and concerns.
Its quite easy, if time consuming, to do yourself.
On a small car like an fto, honestly, you'd probably only need one bulk pack. Invest the money of the "Second" pack on stuff like foam underlay (goes under your carpet to block out road noise, which dynamat simply wont do).
Properly applied, (ie, surface cleaned then prepped with wax and grease remover, then applied firmly (preferably with a roller) dynamat *extreme* wont come off, no.
Cheaper stuff (flashtac, bostik) will fall off, even properly applied. Doesnt sound like a big deal untill you touch SD. Its...sticky. If it peels inside your doors and hits glass, you will simply have to replace it. Let alone how much of a bitch it can be to "redo".
