Greetings!

I'm in the middle of soundproofing the front doors of a fabia, but after taking off the plastic doorcard, I am kind of uncertain about some things. Maybe some of you can help me. I would like to take off the inner (silver) door plate as well.

1. On the inner silver plate (see the picture) are these things rivets or not? I hope not.

2. Is the sealant between the inner silver plate and the door frame going to be damaged if I take the plate off? Or I can reuse it when I put it back...

3. On which side of the silver plate would you put the acoustic material? I think it would be better on the back side...

4. Has anyone used the Sinus Live ADM sound insulation material (it's a bitumen type material)? What do you think of it? CARHIFI von www.sinuslive.com

Thanks!

In answer (done recently to replace a window mechanism:

1 No its a locating pin on the silver plate that fits in a hole in the door frame

2 no it's a foam seal (like draught excluder) stuck to the silver plate and on mine came off the door frame cleanly

3 agreed, otherwise it's likely to foul the inner trim or stick to it

4 No idea but most people seem to use either stick on DIY lead flashing or dynamat which is similar

Edit:

By the way to get that door plate off is a bugger... you need to remove the window glass (large round black covers at top of right hand picture, lower window slightly, loosen bolts and remove upwards) then remove most of the wiring and finally lower the plate off the frame (the top of the mechanism is above it inside the door frame) then reach inside to remove more wiring from the door lock on the frame and then extricate the whole thing off the door lock pin etc.

You might be able to get at it to fit the deadening by removing the window and loosening it all but not removing it though... Is the gain REALLY worth it given you may break something and end up with rattles?

Thanks for the useful answer.

After reading it and some other posts (http://www.briskoda.net/forums/ice-security-insurance/adding-extra-insulation-wiring-front-doors-fabia/77777/ , http://www.briskoda.net/forums/fabia/query-removing-inner-skin/19495/ ) I realized I dont yet feel confident enough to remove inner skin. Too much tricks, possibility of failure like breaking something, water leak, remaining rattle etc. I tried to remove the plastic caps in the windows access holes, but they just hold very (too) strongly (and I suppose this should be the easiest step of the process). Is there a trick to this?

I am now thinking of just fitting a small piece of deading material to the outer skin through the speaker hole, so that right behind the speaker the outer skin is deadened. After this I will also deaded the inner skin. Maybe this will be enough to gain noticable difference.
