I am doing a full install on my car atm, and been using a combination of 4mm Silent Coat, 2mm Silent Coat,
and some 9mm thick CCF sheets
to deaden panels and cut down on unwanted noise.... a lot of smaller gaps
in the rear of the roof were layered up, and once everything was level, then a full coat was applied as the sunroof
is quite well reinforced with cross members etc.
Front seats out first
then rears etc
then headlining
Just a quick note, the rear deck cover is in two parts, a hard plastic front section and a carpet covered cardboard
rear section, there are silver screws around each 6x9 hole, and these hold the two parts together. It took ages to
get the rear shelf off as the brake light hits the rears screen and it hasn't got enough clearance to pull off to get out
of the way etc. Separating the shelf made it much easier going back in, and pretty surer it would have taken us a
fraction of the time to remove it. Once the screws are out, pull up the front edge of the carpeted section and get
that out the way would probably be the easiest for removal.
filling voids
Rear deck coated above and below
more roof deadening
Getting dark so needed some light
Don't forget the front too!!!
The cage that houses the Courtesy lights and sunroof controls & alarm sensors needs double sided sticky
foam tape between it and the roof,
otherwise with the amount of bass going thru the car would make it rattle
really badly, and I didn't fancy taking the roof lining out again either to fix it later!!
I hope these pics will help anyone attempting this, but obviously my car is being soundproofed for an ICE install, not just general soundproofing. I have much more to do including the boot, bootlid and the doors yet, will take a fair while longer than guesstimated, but the job is being done pretty thoroughly, so slow & steadfast will get the best results......
