anyone make their own door panels???

I have a few resto shops here that use Luan. Probably paint it to seal it from moisture. I agree, I will glue thin plastic sheeting over the door like factory did also. I want a vinyl that has good UV protection thinking maybe Marine grade would work if they has the color and grain,otherwise I will look elsewhre.
I have2 cars to do, so I need t make good panels, one being the 62 Lancer and the other is a 64 Savoy SS type recreation.
Gary Ball, In. does great work but $800 for non oem panels is steep for me.
