I'm one of those guys that SharonA mentioned that slaps stickers all over my cases. After a few of my stickers started ripping, I put a coat of verathane on the case and that seemed to help, but now, after over 40 years of wear and tear, one of my banjo cases and a guitar case are sarting to come apart at both ends of the top. These have some very sentimental stickers (the 1961 Mariposa Festival in Orillia, actually the cover of a program glued onto the case) and I don't want to discard the case. Is it possible to fiberglass the case and still be able to read the stickers?
