Ally door skins

[jvrenaudon]

I have two questions. First, what is the anti-drumming material which is adhered to the inside face of the door skins on a CSL? Second, what is the best material to use in order to isolate the skin from the door chassis? As always, any help gratefully received.

Go to one of the aftermarket stereo shops and get what they use. Otherwise, chase down some Dynomat.

The original appears to have been a tarred felty material similar to roofing felt, but thicker. This from my 3.0CS, not a CSL.
