im thinking about painting my interior black, or a greyish color. im just wondering what is a good spray paint for interior. i just used some dupli-color on my fuse box cover and it came out hella shiny and black. a little too shiny for me. i would prefer a more "OEM" look to it, with just a color and no real shine or anything. if i added clear coat, would it also give that "shiny" look to it? and do you guys suggest a black interior, or a more charcoal grey color?
