As has been stated above, this looks like an 'in the making defect' not after the process. This defect should have been seen by a long list of people at the factory, from the worker on the mold, the paint sprayer, the finishers, then finally quality control. If not by them, then by the people who received it at the store you bought it from.
If the bike was stated as new with defects, I'd let it go. If it was not, then I'd be chasing it up. Yes, maybe it was clearance, but this should have been stated and you should have been told. I wouldn't be happy with it and you are not, so ask for a replacement or some extra cash off the sale.
