Plastic Window - glue?

[DrCactus]

Hey folks, so currently I have a crack in the rear plastic window and I won't be getting it replaced for awhile. In the mean time, I been using duct tape which does not work well in the heat and rain. Is there any product out there that would work better to cover the crack that sticks? Or maybe there is some liquid plastic kind of stuff that I can use to seal on the outside and use some flexible tape on the inside? Looking for any options and suggestions.... feel free to add a link or so to products your suggesting too please.

Thanks everyone... ride safe!
