Fibreglassing rear tray

[Provo]

[color=#000000ost_uid0]Hey guys...i thought that in order to keep things simple...i'd just try fibreglassing the rear tray and inside front door as SD? Can anyone see any probs with this...or has anyone done it before?
Cheers,

[color=#000000ost_uid0]fibreglassing the rear shelf would increase the strength of it, but i'm honestly not sure how well it would work as sound deadening...

but then again, plenty of people make speaker pods out of fbg so it must have reasonably good sound sealing properties[/colorost_uid0]

[color=#006666ost_uid0]yeah I think it would be better to use Brown bread or specific sound deadner

fibreglass isnt dense enough to make a difference[/colorost_uid0]

[color=#000000ost_uid0]fibreglassing the shelf will work as sound deadening coz it will increase the mass, but really isnt the best way.
Its too brittle as well. it wont absorb the vibrations well.

proper sound deadening stuff would be best, brown bread ( easily available from jaycar ) and FlashTac ( hardware shops ) are the cheapest and easisest to get. A can of spray on deadening or deadening mats from KMart or wherever would be good too.

Same thing for doors.[/colorost_uid0]

[color=#000000ost_uid0]Yeah well...for the rear tray i've decided on fibreglass for strenth and to stop flex, with SD mats on top of that for most of the SD'ing work.
For the doors... The actual trim, ir not the steel part of the door....do most people SD that?

[color=#000000ost_uid0]yes, its best to deaden the 3 inside layers of the door :

The outer shell,
the inner shell ( including covering up the service holes )
and the inside of the trim.[/colorost_uid0]
