want to attempt to try and soundproof the majority of my 90 for various reasons... Ive read about bitumin based stickers which i already have under the bonnet and its great, but im looking for something to in the door frame, footwell, rear door and basically all of the back as its just bare metal around the glass. It does have a full floor rubber mat which covers the wheel arches inside but thats about it. any pointers would be great
cheers
