Again, I appreciate all of the suggestions for removing the unwanted reflective tape on the fenders of my vintage Raleigh. I tried a bunch without making much progress, and finally had success with heading them with a hair dryer (a torch had been suggested, but I worried about underlying and surrounding paint, nearby decals), rher carefully scraping with a small block of wood with a well-defined edge. Followed up with Goo Gone to remove remaining residue. Worked very well! I’m attaching before/after pictures. Keep in mind, however, that the rear fender paint is not great as it is, and the white already was worn and fading. But white paint was protected under the tape so it left whiter patches where there us3d to be red tape. But it is still less conspicuous than the ragged strips of red tape!
