The window seal currently on the Supra is much thicker than the OEM new one I bought. What the hell? I wish some things could just be straight forward :mad:

Thoughts???
The last 2 hatch glasses I installed I didn't use the dam at all. In talking with a local glass guy that's been doing it for the last 30ish years, the urethanes used for window adhesives have advanced significantly and the dam is no longer necessary.

Window isn't flush against the hatch, so the urethane would need to be pretty thick?
Correct. You'll want to measure the thickness of the glass pads and make sure you have a thicker bead of urethane than that all the way around. Once you get the glass in and settled down to height you'll want to give it time to setup, and then you can go back and trim any excess urethane off.

Also make sure the glass pads are towards the inside of the window and put a bead of urethane around them as well. Not sealing those in can, and usually does, result in leaks at that location.
