nobody wants to do leave the lip polished. I just painted the front two and I am not getting a smooth texture like i wnated, there comming out reall rough. So I am going to have to spend alot of time working on them to get them as smooth as i want them. They are not smooth because the rim has a texture to it to begin with. I am going to wait and let the paint cure completly and use like a 400 grit sand paper on it, then paint more coats on it then clear coat it. here are pics.
