What chris said but you may want to use an adhesion promoter for the plastic to help the primer stick. On my dash all we did is clean, addhesion promoter, about 8 coats of high build primer, wet sand, moere primer, wet sanded and painted and cleared. we also added a flex agent to each coat but that was just because the center part of my dash is that foam backed vinyl and I didn't want to remove it so that it would look factory, only smoothed and painted.
