I just noticed an area of exposed aluminum on my wing root, about the
size of a quarter. I am not sure how and when it got there. Exposed
aluminum seems like an inherently bad thing. Is there some good way to
do a do-it-yourself job of touching this up that is both effective at
protecting the wing and looks decent? My wing is white.
