If you need to recover the complete wing I would fiberglass it . If you are just patching the covering and repainting you can use most iron on coverings .
To paint it I would take a piece of the original covering to home depot or lowes and have them color match it with some exterior latex paint and spray it on . If you are using glow power you will need to fuel proof the latex paint with an epoxy clear coat or urethane clear coat.
