It was basically just like a sub enclosure. The first layer is fiberglass cloth, then fiberglass mat, then bondo hair over the areas with the metal plates ( we will get to that ) and then bondo, and finishing gel, block sanded them then prime, paint, clear, wetsand, and buff. Before I primed them they were an ugly combination of pink, red, green, and a yellowish. They are mounted the same way the OEM leather panels are. Just metal triangles that stick out through a hole in the door panel that you bend up and they come off. The individual leather panels have 4-5 mounting points per piece and mine has 6 total. they are perfectly stable though.
The piece behind where the actual door handle is was harder. Had to carefully take off the leather and foam so I didn't ruin them. Then soak and rub off all the adhesive left over. They are just black plastic so I prime, paint, cleared, wetsand, buffed them.
I also used door trim oddly enough around the fiberglass plate. It looked better than the edges of the fiberglass. I think the next set I make I may try a few things different. Anyone have any ideas? Other than CF. Thats on the menu too.
So what does the unpainted piece look like? Any pictures from the back and how is it mounted to the panel?
I'll post a few photos up later on also.
