Hey Micky, great project...I’ve been watching in the background for a while. I just rebuilt the windshield on my cruiser, and I ended up using Dow U-428 primerless urethane windshield adhesive. I used it to bed and to create a new gasket for the glass, and it’s worked well. You want thickness in the bedding, so I used twine hot glued down in spots as a spacer, the laid a bead of the Dow stuff over that. Once it was set, I trimmed off the excess, back filled the gaps, then flipped it over and used it to make a gasket bead. It tools nicely as well.
Thanks!
