Sami,
Need to answer what caused the paint to come off in the first place.
Impact? Corrosion? Touch up is simple. If you use spray products mask
off all the windows on that side.....

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.
