I have a '74 Excella. The Vista Views have had the interior plastic lens removed and only the glass is left. They are the kind of VV's that have the snap ring on the interior of the opening.
I have searched countless threads on the proper sealant to use to adhere the glass to the inside of the aluminum frame (Vulcem, Sikaflex, TremPro, etc.). Sikaflex was used about seven years ago to adhere the glass to the frame, but a number of the VVs are now leaking at the glass/metal junction (not the outside of the frame. Some VVs have even separated from the metal frame altogether.
Before I use Sikaflex again to reattach the windows...
Today, it was recommended that I use a urethane Automotive Windshield Adhesive (like 3M #08693) to attach the glass to the inside of the metal frame. At first blush, it sounds like a brilliant idea - cars endure the same road conditions as Airstreams, and (although its possible) I've never seen a glued-on automotive windshield separate on its own from the metal structure it is attached to, or leak, (like my Vista Views do).
Any thoughts on using a urethane Automotive Windshield Adhesive for this job?
