Sound Deadening AU Front Doors

[Hords]

G’day All,

I’m wondering if anyone out there has had experience in sound deadening AU Front Doors.

My main concerns are covering the inner door skin service holes before applying Dynamat. My intention was to use duct tape and MDF. However the problem with the service holes is that most of them aren’t on “flat” surfaces making it hard to cover using MDF. There is also a pouch on the door trim which protrudes into the inner panel once the trim is reattached. On top of this there are also several plastic alignment tabs which are also part of the trim. I was simply going to cut these off so their corresponding holes can be covered and sealed.

Also, what would be the best method to apply deadening to the outer door skin? Here I’m stumped about the anti-intrusion bar. Would it be practical to apply a sheet above and below the bar and then cover the bar with a small strip, or just cover the bar with some brush-on deadener? Or even don’t bother with it?

Any help on this subject would be greatly appreciated.

Cheers,
Rob
