The tape on the outside of the canopy was removed after sanding down the old filler to glass transition. I then cleaned the canopy and put down a new tape line that will be used for final filler and contour prior to skim coat and primer. I also blue taped the entire canopy glass to protect it from past lessons learned :) I then moved on to the locking ball pins. I drilled out the longerons to 1/2" and floxed the caps inside while the pin was in place. After cure I removed the pins, closed the canopy and confirmed that the canopy will stay put in both taxi and locked position and I'm pleased to say it works better than I hoped. :)
