I am 15 hrs into phase 1 and my pilot side vent has already come unglued. Installed per plans. And yes I scuffed the mating parts and cleaned with solvent prior to installation. I originally installed the black plastic vents but since I have to reinstall I went ahead and ordered the aluminum vents from vans. On re-install I will try a different glue and possibly a few rivets if possible. I set the nut you spoke of in epoxy/flox mixture.
