I will be painting a new Vader dome for C4 this weekend and need to get a good gloss black. I had read somewhere that it is best to spray it flat (or use black primer) and then hit it with the gloss clearcoat (I can't find the link for this anymore though ). The reason given was that the gloss clearcoat does not stick well on top of the gloss black. They also said it actually turns out less shiny. Has anyone had any experience with this?
