I have a 1969 Camaro with dark blue interior. I've found the right paint code for metal parts. I am also familiar with the gloss percent in various places.
Can someone tell me how the dash pad should be painted? The metal parts have a slight bit of metallic flake but I imagine this shouldn't be the case for plastic stuff like a dash pad, kick panels, or console.
One option is take a look at the color chip chart for SEM Color Coats for a very close on the shelf Blue that matches (best or very close) to a portion of a part that has been protected and hidden from UV and exposure to the elements.
Most of the plastic parts were molded in color. Dash cluster and console were painted.
