Talking about Leather... it's all in the GLUE!!!
I've been told the major issue with 928 leather interiors was caused by glues that softened under warm temperatures and allowed the leather to move.
So I asked someone what glue Porsche uses nowadays for their interiors. And the answer was "HELMIPUR".
After some research I found what I believe is the manufacturer's websiite, which unfortunately is not very specific about the name and type of HELMIPUR that would be suited for interior leather. They do have a page about this topic, and it's kind of lame:
http://www.forbo.com/framework/Deskt...u_id=158&ssm=1
But if you want to find out, maybe the US reps can help:

Just thought I'd document this here for potential future reference....

Maybe. Dashes were glued and I have seen dashes fron early cars where the glue was still intact, and the leather had shrunk, pulling the underlying vinyl at what must be immense torsion, up and out. Rear quarters certainly are not glued as well, and if ther were, e would see the same there. In my opinion, the problem is, the underlying vinyl on the dash and underlying cardboard on the quarters simply cannot take the stresses imposed by shrinking leather.
What should have been done, was to use a steel mould to which leather was glued. We could still have this done cheaply I think. leather over garbage will always fail as it shrinks. Nicole, in my experience no glue can help here.

Not something I wanted to hear as I am getting ready to recover my leather dash this winter. I was hoping to remove what I thought was 2 layers of leather to get to metal, but I was told that you can't remove the vinyl under the leather as it creates the shape for the dash.
As far as the glue, contact cement seems to be what everyone is using.
