P-K screw rusting. The top of the screws always look ok. It’s when you loosen it up where you get the rust under the screw head. All of them are being replaced like I did on the other wing. All the screws are out and corrosion prevention applied under the leading edge.
Just when you thought you were ready to cover too huh? Sounds like you suspected that though! Leave no screw unturned, right? Ha!
