paint problem need help please

Sounds like the clearcoat catalyst has not kicked off yet.Ask the painter what he used,call the company that makes the paint.The catalyst needs drying time.Judging from the amount of time it has sat,not enough clearcoat catalyst.If you can ,set it in sunlight.This may take a few days.Something is not right,even the slowest clearcoats in the coldest weather usually kick off and harden in 7 to 10 days.
