I cut out the triangular inlet for the vent system for the right wing, cleaned, alodined and primed the internal ducting, and only cleaned and clear-alodined the more visible portion. I used Avex rivets, which are not grip sensitive, to secure the duct flange to the wing root, and installed nutplates to secure the vent to the inner rib. I cleaned up and prepared the other wings vent system, as well.
