My problem is that the cloth-covered portion of my 1998 Malibu door inserts is peeling off and looks terrible. Rather than re-glue it I thought maybe I'd try to go the creative route and put something else in there. Does anyone have any ideas?

I am going to be removing the vinyl from them and fiberglassing over the cardboard mold so I can add some things to them. Therefore, extreme suggestions are fine as well

I was thinking maybe laying a flat panel of brushed aluminum in there or maybe some vinyl instead of cloth.
