Adhesive to use on window

[JRS]

Thanks all for the responses!
Our original window at about 3-4 months of use literally disappeared on a trip (fortunately no damage experienced). You can imagine our surprise when we stopped LOL! It was changed to a window that pivots from the top. The new window attaches to a rubber membrane (not glass, metal or plastic). Thus the reasoning for using the 3M 08609 I mention above.
What gets me is the glue/adhesive on the current window is actually sticky which leads me to believe it's not epoxy.
Thinking now I should use the 3M tape mentioned by Rich above and due to the positive results with Scott using a tape.
Thanks again for all the suggestions everybody! I really don't want to buy a window (which Lippert advises LOL)
In the fall of 2020 (we picked up the rig in Sept of 19), Newmar also looked at our other windows and determined they were OK.

Like what RichW says about using UHW tape. Personally I would etch the bonding surface with Hydrofluoric Acid paste before thinking anything was going to stick to such a nonporous surface.
