remodeling armature board and facer front

Good evening dear community, I have 2 questions for you… 1. I’ve got this leather look from the armature board and the doors and something boring… So I wanted to stick it with a good 3d carbon foil. I wanted to ask if someone knows what I can take the best for a substrate…so something like silikon (which I can do on this “leather” and what remains “emollient”) just stick to it. And please don’t tell me to take the door pads from the facer…I want to keep my living room feeling… 2.I wanted to replace my front bumper with the one from the facer. Maybe someone has the stuff of what I need to lie around and could you offer me? Maybe also the decorating of the facer? For the combo… Achso: does the roofing strongly contribute to stability? I wanted to remove you… and I don’t know quite because of safety in an accident (it can hit anyone) Many thanks in front of it With friendly greetings
