Wing spar follow-throughs

Micro-camera in the wing spar follow-throughs showed some surface corrosion. I’ve pulled one of the spar mounting blocks for a better look and it may be that it looked worse on the little camera than it is. I’m going to gently scotch-brite the interior of the box section to clean it out as much as possible and then stick the camera down again.
