Sound deadening material
Hi all I'm looking to order some sound deadening material under my bonnet.. There seems to be several makes.. Dynamat, dodo, silent coat, stinger stealth... Has anyone any experience of these;.. I'm going to do the floors and inside the doors as well .. Obviously.. Heat and moisture resistant is important under bonnet.. Will order something this week.... Once I have decided... Your advice would be appreciated
Hi John
The 460 Insulation is NLA as you know
I priced a 463 version for Howard Green last week at around £150 and available
Can't see why it would not fit, in all honesty it looks identical
Also saw one last week or so with Insulation fitted like your thinking and looked great
Can't remember if it was Adrian Cox's or Mark Ashton's
Maybe one will chirp in..

Hi Pics of my re-work for under bonnet deadening.
Given the amount of possible places for noise to get out of a 460 engine bay the idling noise is 'softer' by about 10% however it is a lot more refined at higher revs/speeds..
Mind you I think the bonnet now weights about 60lbs :-) definately shuts with a 'thunk'

PS: I could just have used the noise killer
I put the sound deadening today.... underbonnet and entire rear floor and arches...
the bonnet is really heavy and closes with a dull thud rather than the zing of resonating sheet metal... time will tell if it makes any difference.... each sheet of 'Silent Coat' is only 2mm thick and heat resistant... but is very heavy.. self adhesive... about 12x18 inch sheets which make them easy to handle and shape around different parts
Did it make noticeable difference in road noise John ?
Hi mate...
I went for the Silent coat kit... 41 pieces for 77 quid.(Fleabay). i can always add to the underbonnet panel with something thicker on top as these sheets are an amazing 2mm thick... hopefully enough to do the entire car! (Dynomat recommends this approach anyway)
should arrive Wednesday... report of difference by Thurs /Fri...
