Shiny Plastic Interiors? How do they do this?

That link you gave for fiberglassing, you have to be a member, or it doesn't show. At least that's what it did on my end. I think i would sand it with a 600 grit to get the texture out of the panel, then spray it with adhesive polymer, then the color of your choice. Never did the high build primer much. Always ran into a problem with it flaking or chipping afterwards. And adhesive polymer acts as a primer.
