----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- The serious type of corrosion is intergrannular. Untouched it appears as a bubble on top of the aluminum structure. When covered with dirt and grime, the rise in the metal can be very difficult to detect with lights and a mirrors. When you penetrate the raised bubble with a knife or pick, the surface shreds a bit and inside the bubble is white powder. It's found on the upper and lower spar caps of the wing. The spar caps of the center section can have delamination corrosion on the spar caps just above or below the wing attach fittings. The caps are aluminum, the fittings are steel so dissimilar metal corrosion can develop and can become quite serious here. The bottom of the center section spar can also develop corrosion. Surface corrosion appears as a white powder on the surface of the aluminum and usually does not involve destruction that can't be treated. I have seen, however, where this type of corrosion when left untreated has completely eaten away sections of wing rib structure.
