Ok guys, I am trying to remember back from A&P School about corrosion....I cannot recall which type of corrosion this is... (pic below).
Again, I bought my wing kit 2nd hand in April 2010. Little had been done, so inspection of all parts was easy. I knew that it only came with 3 skins. (2 bottom outboard, and one top outboard.) All 3 skins were stored leaning against a wall in a metal shop on a concrete floor. Bottom line, all 3 outboard skins have some of the white powdery corrosion shown above. I HAVE looked at my AC43-13, and can't find what I am looking for there. I HAVE also done a search for corrosion here, and found one issue similar. I have taken a scotchbrite wheel in a dotco, and can fairly easily clean it off. Under the whitish powder, it is pitted a bit. (Again though, I can clean it ALL off with the dotco) I think I can clean it up, alodine it, and then prime. If this is a bad idea, tell me, just be nice about it.
Lastly, out of curiousity, how much 'coverage' of this corrosion would be grounds for rejection of a skin?
