you can try a heat gun some glues will release with the right amount of heat but you'll have too watch no too warp the panel.
anytime i had too remove lamination,veneers,formica or any other substrate that was spray glued(contact cement) I allways used laquer thinner or actetone and a putty knife to help to cut the gooey strings right at the separated seem. although I've never done it too a door panel so before you try it I would test a hidden spot before going full bore. also try some gasoline. I've used gas too take paint off the (abs or plastic) panels in the hatch/trunk of the pontiac and it didnt harm them at all and worked quite well it just required some serious cleaning afterwards also just be carefull with any ignition points in the area

I would imagine with tweed the juice of your choice should soak right through too the glue once you try a small part
