Did more “finishing” work today. Removed the blue vinyl cover at the outboard parts of the top of the wings and cleaned the surfaces with acetone. Sprayed Goof Off gel several times on areas with the hard-to-remove sticky residue with success. Also cleaned the sides of the Fuselage. There were areas with dried epoxy which was hard to remove. There was residual adhesive from the duct tape that I used to protect the fuselage that was removed with acetone and Goof Off gel.
