David said that I should speak to Hasselblad in NJ so I called them and left a message and haven't received a response yet.
I'm not sure if this guy is willing to make a trip Zeiss, lens in hand, to insist that they fix it lol.
I think as others have said, his best best is probably to sell the lens as a parts lens and buy another. I'll check out the polishing guy that Johnielvis is talking about to see if thats an option.
The black paint idea would work to reduce flare but with this lens being a super wide, DOF is more the issue. Especially with the lens stopped down, he'll definitely see the defect in the images simply because of the wide DOF of the lens.
