Plastic inner wing

[duralinox]

I need to remove the protective plastic inner wing at the rear, and I've removed the 2 nuts holding it, plus the screw in the rear bumper, but now I cannot figure out how to get it out. Only solution in my mind, is to take a screwdriver and pull it along the edge of the outer metal wing to get it out, but then I don't think there will be much paint left of the edge of the wing. Have anyone tried this? Help will be apriciated!
