This has been said before here, but it doesn't hurt to say again. This year I cut the wing center section inspection holes instead of removing the wings to inspect for corrosion. I found intergranular corrosion on a small brace on both sides, in between two ribs that are impossible to inspect without the holes. No corrosion anywhere else! So if you haven't cut those holes you might want to do so, removing the wings does not give you a look everywhere.
