Can these panels be saved?

Looks pretty much like it got sun baked and or cooked by interior car temps. I used a heat gun and pulled gently and then a **** load of small clamps with the material bent over the edge of the door card. Let cool and then glued. Try your best pulling with the grain of the already there print to not to distort the pattern.

If I was going to do another I may try a steam cleaner or a damp rag and an iron.
