Unknown sound deadener in 7.5 Golf R Wagon

[Bullet Fast]

Pulled the interior from rear doors back to dynamat the car. Discovered wierd factory sound deadener that looks like panel glue (rather than standard VW rubber mats.

Wondering if anyone has dealt with this on a sound proofing mission?

Had intended for 25-30% coverage so I can work around it.

Looks typical to me on large monocoque elements. Will help reduce harmonic vibrations (thrumming) without the need to apply deadener to a whole panel.

Yes, looks like anti-drum deadener. Then the overlay/carpet would generally reduce the higher frequency stuff.

Did you find applying Dynamat made a difference?

I had a Octavia RS wagon , very little of any deadening material and it was noisy , Dynamat made a big difference .
In the good old 80's had a BMW 735i , lifted the carpet one day, LEAD sheeting , now thats a winner , no wonder its was a heavy car.
