Though I don't really know if this is proper, I've seen a couple guys paint their dashes in bumper coating black. I believe it ends up drying as a semi satin black and it is a very thick coat of paint. I believe the dashes originally came either a flat black or semi satin black, but I'd wait for someone else to confirm this for you. Here's a Duster that had the dash painted with bumper coating black. The dash pad was redyed using SEM's vinyl and plastic dye.
