Shrinkage is an issue very difficult to fix. My door pocket lids are back from the upholstery shop and look really good. They are a bit lighter since the rest of the leather is 11 years old. I'm good with it. Eventually I hope to rid the car of all this #@*& wood trim. Shame on Porsche... Terrible laminate and certainly no easy fix.
I used a hot hair dryer on high for about 2 minutes (held about 3" off the subject surface). It did soften the material enough to allow the contact cement to hold it when dry.
BTW: What part of the planet are you on? I'm in Northern AZ, USA.
