I have been using meguiars #7 hand glaze on my 68 coupe, for a couple of years. The paint is Acrylic urethane or Acrylic Enamel, I can't remember. It has not been waxed since the paint was put on. I'm trying to get a little better shine out of it. Will I get that with the gold class? Or do I have to go back to the polishing stage and start from there?
