I have to believe the window is rebuildable-sealable with 3M 5200(black). 5200 will stick to anything and take a few days to a week+ to cure up(forever). You can put a nice surface/control the bead laid-down bead by dipping your (glove covered) finger in toluene or xylenes as 5200 won't stick to it. %200 will still cure up fine..not affected by toluene or xylenes(also sold as xylol).
Again..I haven't seen one up close, but I'd strip any seals out of it and keep just the frame and glass. Everything else(seals) would be replaced/rebedded with 5200. You may have to seal up some edges with tape/tinfoil to keep the 5200 from flowing out, but it can be removed after the 5200 is set up.
Practice with managing 5200(applying it, removing it, forming it with xylenes, containing it with tape/tinfoil..) before you dive it..it can be messy if you're not prepared to handle it.
Whatever you do..don't use silicone first..just makes things tougher.
This last round was 5200. I've used it a lot on our race boats. I seriously thought I nailed it this time. Went 2 months through a bunch of storms without a leak! Then the other morning I came out to a wet spot on the corner of the bed. Big waste of time and money.
