Duct tape and fiberglass
In a fit of desperation, duct tape was used to cover a hole where the autopilot control head used to be. It was then left on for the last 1-2 months of the season, and not removed until recently. Now, of course, there is duct tape residue on the walls of the cockpit surrounding the hole.
Does anyone have suggestions for removal without damaging the finish on the glass? I have considered: denatured alcohol, mineral spirits, methyl-ethyl ketone, acetone, jackhammer, drill, and sandpaper.
All good non-destructive ideas are welcome!
