You will find that there's a lack of closed cell foam or any for of thick wadding under the rear floor liner.  I'll be buying some 20mm closed cell foam and applying this later.  I'll double up on this under the seats, as there's plenty enough space for 40mm+.  The Silent coat mainly acts as a layer to reduce NVH, as such it does dampen the cabin noise slightly.

I'll also line the back of the plastic trim panels with 20mm of closed cell foam too.
