Guys I have had the same problems all over...
I have a sedan and what i did was fill the boot-lid with space invader that
foam filler they sell at the hardware. Make sure you tape up all the places it can
expand and leak out of with duct tape. Is this dynomat stuff like brown bread? If
so i haven't found a cheaper alternative yet... I have found a cheap supplier of
the sound paint.. (if in Aust) just email your details or questions to
gsperformance@optushome.com.au and i am sure the guys will get back to you.
I think they have a bit of that woll/tar backed material too which is cheaper than
jcars price.
Thicker/new seals are always a way to go to.
