MarkBean,
With your factory-matched touch-up paint (usually available at the dealer or auto parts store), you can use a product called Langka (
www.langka.com) to help smoothen the "blob." Using it is a bit of an art form, but the results are quite nice. If you Google around, it's discussed quite a bit on other forums.
Prior to that, I'd probably clay the surface to remove embedded contaminants. After just washing your vehicle, run your fingers lightly across the surface -- if you feel little bumps, you really need to clay. Under normal circumstances, claying should be done once or twice a year (if not more). Mothers and other major makers sell a good consumer clay bar. In the Mothers Clay Bar Paint Saving System (a kit) you get a clay bar (enough to clay two or three cars), lubricant, and you also get a sample size of their Carnauba Cleaner Wax which has some pretty aggressive polishes as cleaner waxes go. Give that a try.
That particular Zymol, I understand, has fairly mild polishes and probably won't "restore" the finish to your liking.
