Looks like that will work. If the model wasn't already painted, it's easy to make them from scratch using bits of clear sprue. After cutting a notch in the wing and cutting an oversize piece of clear sprue to fir the notch, glue the sprue in with CA and then shape it with files and wet/dry sandpaper to conform to the wing. Polish with very fine paper and brush a bit of gloss clear on it to finish it off.
