Custom Interior Door Panels

So I thought I would take a page from @Oldschoolcuda and more or less copy what he did to replace the very sad door panels (cards) on my '66. Here is a picture of what it looked like to start. Originally, the car war dark red poly paint and black interior, I think. Later painted black and a funky silverish interior job installed.

So these were painted a kind of silver and may have looked decent when first done, but I doubt it.
