Nadine,

I used formica scraps. They hold thier shape better and you can use contact cement to hold the upholstry on the back side. I also laced the back side top to bottom and side to side with fishing line just in case the glue decided to let loose on a hot day. Behind the door handle and window crank I cut plastic washers from frosted coffee can lids. It didn't take but a few hours to do both doors and they looked great for the couple years I had the truck after that. smile
