I always clean the removed safety glass spotless then caulk it to the masked off edges of the CRT face....I see that as being a period correct safety solution. Before bonding there was always a separate plate of safety glass in front of the screen mounted to the cabinet, and that was seen as a proper/sufficient safety measure at the time. When bonded safety glass came on the scene, for a few years it existed along side a non-bonded version that consisted of the same piece of glass with a rubber gasket around the perimeter that was held to the CRT face with the CRT mounting hardware. Ever compare a 21FJP22 with a 21FBP22? The way I see it converting a bonded tube to an edge caulked tube is no different than converting a 21FBP to a 21FJP, and should be just as safe as a factory original 21FJP once completed.
