On the Cinelli SC I am completing the touch up on I have a decal between the shifters from Cycles Selection, the shop in Geneva Switzerland that originally sold the bike. I love it! However, it is loosening around the edges and I feel these edges should be stuck back down before I start applying paste wax. On a piece of furniture I would know exactly what I wanted to do (write if you want to know) , but on a steel frame bike that will get wear and tear I am not at all sure what I should use to stick these edges back down and prevent the eventual loss of this sticker. Having been on there since '77, I assume it is really stuck on pretty well, but those loose edges bother me. I have invested many hours to save the original paint and decals here and hate to screw it up at this late date.
Any suggestions?
