Several years ago it was discovered on VariEzes that the aluminum wing attach fittings had corrosion like this and some of the aluminum canard elevator torque tubes in Longezes and Variezes had a corrosion problem. The highly recommended solution was to have these aluminum parts anodized before installation to help prevent this problem. Take note that most of the problems were with airplanes that had been built and spent most of their lives in coastal places like Florida, near sea shores where salty air can be a problem for aluminum and especially aluminum airplanes. Ever since I have been in the airplane owning game, all the old guys that taught me always warned me to not purchase any airplanes that had spent time in coastal areas. Might be an old wives tale but it makes sense to me so I have always followed that advice. Larry Howell
