This re: my 1962 Globe Trotter's Hehr 1200 series (Mark 12) flat glass windows- I figured out how to measure the thickness of my original (still in tight with factory mastic) flat glass panes. It's .090", meaning single strength glass. That may explain SOME of the difficulty I was having working in the new Hehr 009-311 glazing bead on the broken pane I replaced with double strength (.125") glass. This new material (009-311 glazing bead) certainly appears to be more than cosmetic as I install it on my windows, although the original brittle plastic stuff didn't seem to be doing much. If the factory mastic tape adhering the glass pane to the frame has a good continuous seal, that would stop water. The mastic has let loose in a few little spots on some of my windows, but just small spots. The glass is VERY hard to get out if the mastic is still doing its job, so I'm not removing the original panes. I'll do a little spot caulking there. But the new rubber glazing bead (009-311) I'm installing (outside the glass) does appear to perform the functions of helping to hold the pane firmly into the frame (whether it was meant to or not), as well as being an additional seal against moisture getting around the edge of the pane.
