Try the various touch up paints first and if you are a PCA member, go to a concours clinic and learn how to do this correctly.

The problem with a respray is the depth of paint is instantly detected by a knowledgable PPI specialist (with their gauges).

If you use a product like Dr. Colorchip, let it dry longer before you rub the "magic" solution...also do not rub hard; you'll remove all the paint you just applied.
