How about Quilted Wing Protectors?
This is the near side Protector, viewed from behind. They are made from two layers of old curtains with a generous layer of inter-liner material for shock protection. To keep it in place (without the need for dancing girls) there is a large "button hole" for the wing light and three rectangular cut-outs for the bonnet catches and buffer, all edged in zig-zag stitching to stop the material fraying.

Finally, the quilting foot keeps the layers together. The Protectors in action!!
No wings were harmed during the making of this Post! P.S. fits both cars.
