Firstly a big thanks to @Apportable for one of his brilliant idea's!
I am in no way comparing this stuff to Dynamat or any other sound deadening product but it works!
I decided I would try it on both front doors. There is limited access so it's not just a matter of cutting lengths and sticking it on.
It has to be cut in strips and fed in place piece by piece. I used a hairdryer on each piece for about 15-20 seconds which just made it stick essier.
I think the reason why it works so well is that there are two crash bars running across the door width..one top and one bottom.
They are bolted each end and Rover used a few blobs of glue between the bar and the outer door skin to stop rattle but they resonate with the door skin.
I wrapped pieces around each bar and everywhere in between. It's a bit fiddly in places as you have to feed it through the apertures and work blind but I made sure I covered as much as possible.
I couldn't wait to close the door and as M says they clunk now without that zing or rattle. That was sounding hopeful so I went for a run and noticed the difference immeadiately.
I have to drive down a forest road before I hit tarmac and it was so much better. Scuttle shake did not set the doors off.
I am a musician and on stage if the bass player plays a note in between songs the snare drum will rattle in sympathy and I believe those bars and the door skin were doing the same.
It's not that this tape has miracle sound deadening properties but it did stop that resonance and in all honesty I am blown away.
To be continued...tomorrow I will buy another roll and stick it to the engine bay cover, under the bonnet and maybe in the boot lid.
So far I have done the floor pans, behind the seats,behind the dash but the biggest difference has to be the doors.
Instead of a rattle it "clunk's " and makes it sound like a different car.
