At the time I did my dash frame, column, interior door, and metal sail panels with Sikkens Ralley Black - also a two part that looks like the hot rod black (low or semi-gloss). I just didn't care for the factory suede which is quite flat. Not quite as glossy as it looks in the flash photos below. BUT, if authenticity is important, then stick with the suedes.

And I love SEM Landau Black in a rattle can for the plastics.
