There are various ABS repair products out there.
I would drive over (not phone) and try to talk with an auto body repair and paint shop for advice. They might even have what you need on hand.
I once used fiberglass (resin and cloth) to repair abs. It held up good for a while, but it wasn't that it was fiberglass, it was because I lack the skills for such work.

Did you mean an "1800" Wing?
