I know there's been a little discussion on this before, but I haven't read a tremendous amount about the topic. What is everyone's preferred method for restoring the non-black interiors, specifically the plastic parts?

I've got E-bodies on the mind, so that's mostly what I'm wondering about. Were all the panels molded in their various colors? When I see this topic comes up the new Metro panels get mentioned, and SEM dye.

The Metro panels seem to be limited supply, but if that route is used, how well do the colors match? If using OE panels, how well does the dye work? Is it best to start with a set the proper color and dye, or dye black ones? Is SEM the only route? How durable?

Just curious hearing the thoughts of everyone who has done this before?
