The antique TV guys I know generally let the protective shield float over the CRT with no sealant. Generally they will just support (if even needed) the shield with four dabs of silicone or even just four little bits of double sided foam tape. Those shields really are not needed, except to maintain "the look". Large CRTs have had fantastically strong faces since mid World War 2. Go find a weak ca. 1949 10BP4 (and that is "pre-banding"!) and break it - you will find out just how strong those faces are. -- Will
CRT faceplates / screen "mold"
Many years ago I cut the faceplate off an HP display exhibiting serious decay of the sealant between the faceplate and the CRT itself, cleaned everything up, then reattached the plate just with a bead of sealant around the perimeter (where it wouldn't be seen once the bezel was back on). Short of outright replacing the CRT with one of the same type, is that still accepted practice - or in the years since has someone worked out a way of applying new sealant across the entire face without getting air trapped in there, thereby maintaining the structural integrity of the original? cheers Jules
