As described earlier, I have been able to take off all the foam trim of the dash front without any damage. In europe a full sets goes close to 1500€, so that is a lot of value, and I don't want to cut that in pieces to cover whatever of the dash is not covered by the PCB boards. That is basically everything above the red line on the (internet) picture below. I'll have to figure out a way to fabricate that myself. Spae can be cut and sanded in any material, but more challenging is how to cover it so it gets a factory like finish.
I have found some textured vinyl that does not have a textile backing. So it can stretch in any direction with some heath applied.
The test sample I experimented on was a block of balsa wood.
The vinyl is quite stiff, but a heat gun turns it flexible and stretchable. Before heating contact glue is applied to the back and to the balsa block
The vinyl wraps nicely to the squarest of corners without wrinkles, the glue keeps everything in place.
Once the edges are trimmed off, very hard to see this not an industrial manufactured part. The surface texture of the vinyl is not exactly as OEM Porsche though, but should do it. In the meantime I try to find other sources. All-in-all this technique seems to work so I can start working on these parts. I may not use balsa wood, but water proof mdf for increased form stability and surface strength.
