I ended up using clear silicone. I found out that most solvents will loosen the silicone including gasoline, lacquer thinner, mineral spirits, etc so it should not be too difficult to replace the glass if I ever need to. If you use silicone, I would recommend you let any squeeze out cure for a couple of days to make it easier to remove. I only let mine cure overnight and the thicker spots were still a little sticky underneath and I had to use some solvent to get the frame clean. The thin spots just peeled right off so next time I will let it cure longer.
