I've searched and i'm surprise that this hasn't been asked before.....

A fair few of us have had welding work done to the floor. This means that the black sound deadening would have been hammered off. Has anyone replaced this to keep the interior sound levels down? If so, what did they use? I am looking for something that I can remove and re-use should I need any further welding work doing in the future and thought about this UNDERFELT UNDERLAY SOUNDPROOFING

I just left the sound deadening out. Not really had a problem with that and I can't remember the noise increasing drastically afterwards but I've since fitted a stainless exhaust so the noise in the car can be quite droney at times anyway. Maybe some sound deadening like the stuff you've posted would help but I've just never bothered.

Did doing the boot make a big difference? How many did it take to do the boot? People do say it's really loud in the back so maybe the boot is the best place to start.

Me having the straight through could be quite loud and droney and with the sound deadening in the boot and the spare wheel well, the drone isn't so bad. It took 12 of those pads and that was reallly through, all in the spare wheel well, the boot and a bit of the bottom tailgate. The best thing to do with them is use a heat gun, just to make the glue a little more tacky, but once they go down, they go down! laugh.gif

Cheers Lee. I have just been told that the drone of the exhaust is caused by panels resonating the way to stop this is to change the resonance frequency of the panels. the easiest way to do this is by sticking sound deadening to the panels. Then you can use this sound lining to reduce the noise into the car.

So I have ordered 16 of those panels and If I wish, I can add the fiber stuff on top smile.gif
