Time for another update:
I was asked to seal and do some minor touchup on the backglass,
so the first job to do was seal it with Triple Thick
Then the glass was set up in my backglass jig.
As can be seen, the glass is already pretty nice shape! Only needing relatively minor touchup work.
Some pics of the areas that needed attention; before and after pics!

And a final coat of Triple Thick over the whole lot to finish it off.. and job done!!
