The instrument panel disassembles easily and the individual parts can then be dealt with. Shown here is a complete assembly and one in pieces.
The color change is easy; after a thorough cleaning I scuff the surfaces of the three nacelle pieces with a scotchbrite pad and spray them with a product from SEM called Trim Black, which is used for the black plastic trim pieces on cars, like fender surrounds and bumpers. This is a very durable matte finish and looks factory applied.
While it won't come crystal clear, the finished lens looks very good. Screw everything back together and mount it up.
