I use some thin weather strip around the edge of the tube. The stuff that has the sticky on one side. You center the safety glass and use packing tape around the edges. Go all the way around with small pieces. Make sure it's very clean on the tube face and inside the safety glass, otherwise you'll notice the dirt/fingerprints and you will have to start over. Mine was bonded. Still applies to the non bonded ones if you do not want to use that oily gasket again. You could also just tape the rubber to the CRT to keep it from moving after cleanup.
