Thats the painters error. Its his responsibility to fix, then it should be on him. If you've already gone to that well a few times, I hope hes not your friend cuz he might not send you a christmas card.
That being said; Ive got to wonder how it was missed with 3 coats of clear and buffing. Now; if it has had a cut and buff done; I might worry about it lifting at some point and causing problems way down the road. But I will always defer to Milo, Old Fool and Brian.
If it was a solid color daily-driver kinda thing, I'd make due by leaving it or 'surgery'; this looks like a high end situation and deserves that kind of attention. Incidentally, was it your choice to use Omni?
