Removed protective plastic from the left aileron and flap. To my surprise, I found what looked like some minor surface corrosion on the flap and aileron skins, near the inboard edges. I pulled the plastic from the R wing control surfaces and found similar spots there. I cleaned, sanded and primed several of these areas, and will get to the rest shortly.
(These components have been stored in a dry envoronment since their delivery two months ago, so the corrosion must have occured during transit from the Philippines.)
A bit of minor surface corrosion on the edges of the flaps and ailerons.
