My screws arrived today. Very nice. The set on my Fiero had been looking less than stellar, and I'd been trying to figure out how to restore them, so this was a welcome product.
I actually have a number of NOS decklid vent screws, and they look almost as badly as my used set. These are still in the bag, so so one has touched them. It's just that the black coating is sporadic. No peeling or anything.
