I also curbed my rocker panel a few weeks ago. The body shop I was recommended to by my PDR guy suggested letting them blend the paint on the lower half and re-clear coating the whole panel, ie the whole side of my car. I was worried about clearing the whole side but my PDR guy reassured me that it's the right route. So I trusted them and it turned out great. Can't tell the difference and the clear coat doesn't look any different. Plus lifetime warranty against any pealing that's not from neglected rock chips.
Just my experience but wanted to share incase it helps.
