If its Base/Clear, you can wetsand the entire panel with 1200 or 1000 grit, Epoxy Prime the repaired area, let it dry, then wetsand the Epoxy Primer with 600 until smooth, wash the panel and let dry, final wash it, then blow some color over the Epoxy Primed area until the color is blended, then reclear the whole panel and you should be good to go... Hope this helps
