So i bought a set of 02 door cups to paint and put into my stang. I am wanting a very smooth and shiney look to them. They will be black. I have 200, 600, and 1000 grit sand paper. I have duplicolor filler primer to prime them up and sand them to get them nice and smooth. But my question is what kind of paint should i use on these? I want a smooth wet look. Also i think i would have to clear them too. What kind of clear should i use? Rattle can? Thanks guys.
