I spent a few hours yesterday soundproofing the aluminium rear bulhead with Silent Coat Extra 4mm.
This has made much more of an improvement in bevel box noise than either Millers 140 or Redline 250.
Do you recommend that over Dynamat?
I don't think there is much difference, Dynamat is made in the USA and Silent Coat is made in the UK. I can confirm that the Silent Coat is easy enough to fit and seems to work well at reducing the transmission noises. I have not tried Dynamat.
