When you pay $1200 for an AAR hood, you expect more from Stinger Fiberglass

Your choices are limited....

Can you do the repair and if so what's the material cost?
If you can't do the repair who can and can you get an estimate?
Dispute it, you can win, however you won't ever get another hood from the clown.
Worry yourself to death about this..

That's about it. I agree that it's crap packaging and the owner thinks he is god. Atleast you know where you stand. But it sounds like the hood is fine otherwise. Rarely have I seen fiberglass that didn't need addressing though in your case is slopping packaging.

Pick and choose your battles and you also have the option of a bad Google review when this is all done. They have traction these days. If it were me I'm fixing it and leaving a bad review. The owner set that into motion, not you but it's not a deal breaker for the over condition of the hood and welcome to shipping 101 unfortunatelty...
