Cut you approximately 2''x 4'' frayed end pieces of matt glass. Fully wet them on a plastic surface and use them like tape. Run at least 3 layers on your edges. I don't have any pictures of when I did it on my Murc doors but the bonded very well.

The picture shows the exterior mating surface that I also bonded with glass strips

Thanks Jets!

What about on the upper frame area, do you put any material (panel bond or dyna glass) in between the outer and inner door panels?  Or do you just lay material on the outside of the two panels clamped together?  ::scratch

Yes I did. I used a piece of steel on the upper section to keep my door sturdy and used 3m body panel adhesive to bond the outer shell to the steel as well as the inner shell to the steel. Also followed the edges up with glass because my gap was about 1/2”.

Jets Thanks!,  The 3m 8115 is some great stuff.  I utilized steel in my upper frame.  Probably apply 8115 to the two pieces and clamp in place, let cure then follow up with glass.  Using the OEM window glass was a bit challenging as it required quite a bit of jockeying to get the door to work with the glass.  If there is any place it will look odd with be the upper inner door frame.  But at least I will have glass windows that work :)

Then I back that up with fiberglass mat in a number of strategic locations (as appropriate). Between these two methods, it appears to be really solid.

Thanks for the input Neils!  Yes the 3m Windshield urethane is some great stuff, used it in my headlight build.
