I put a heater in that room in an attempt to improve the cure time of the rubber cement.  I think I'll leave it cure for a week or until I can't stand the suspense.

A friend replaced the inflation type slide seal with this, which he purchased on ebay. bought 200' of it, and secured it in the slot for the seal. Works great. It's 1" high. Might be able to purchase from https://www.steelerubber.com/

I can see where some folks might want to go that direction but I like the inflatable seals.  If the hole was anywhere on the main part of the seal I would just replace it.  Since it's at the fold and still works it's worth some experimentation.
