I second meguiars also. They're make some of the best car products IMO. Since we're on the subject, something that people with older cars like mine should consider is a clay bar, if you've never tried it. It's the best thing to get off dirt and paint-overspray that has accumulated on the surface and cannot simply be waxed or washed off. It's one of the most incredible car products I have used(besides a leather chamosis). Meguiars or Mothers both are good for this.
