Now the question at hand is, "How much does this bother you?" What does this look like at 5 feet? 3 feet? How close must you get to see the marring? How obvious is it? What are you willing to spend?
Is this a daily driver or your "garage queen"?
If it is a daily driver you will wind up spending a bunch and likely get some rock chips the first couple weeks it is out of the paint shop. SH_T happens, at least it does to me, all too often.
I have a garage queen and I spent a small fortune to achieve what I wanted. I knew how much it would bother me to have imperfections in the paint that probably only "I" would see and yet no one else would likely ever notice.
A good painter can make your issue go away. Keep in mind that you will need to spend some time with your chosen painter and shop owner explaining that you are adamant about your expectations before they ever begin. Be sure you and they are on the same page and have the same understanding of the definition of "Flawless".
I had my shop redo my paint as it developed tiny solvent pops the first time they tried. They finally did it perfectly but it took them three months. We were both very proud of the work they did.
Repaints are often not as good as OEM unless you have a good budget and can find the right shop and painter. Collision repair shops are almost never the place to expect a great paint job. Find who does custom work in your area? Who paints the custom rods. Go to a few car shows and examine the paint on them and ask the owners who painted them.
Lastly, look at this as an opportunity to do something outside the box. Don't just seek a repair. This is an opportunity to do a couple more significant things that could make your vette a one of a kind standout. First to remove all traces of the famous GM orange peel, that is present an almost every GM vehicle I've ever seen. Second, thought about custom paint designs color blends, shading? Third, what about wraps?
Good luck.
