I needed to attach a piece of plastic to my toilet and tried it. It said it would work in ten minutes, but just in case I taped the part for almost two hours to make sure it dried and had time to cure. Then I pulled the lever and the piece broke and fell to the ground. There was no reason this should have happened as there was enough glue, there was enough time and the part wasn't tiny or deformed from cracking. It just needed a good gel glue to actually set it up and hold it in place. I didn't try to leave him alone overnight or anything because I'd already given him way more time than he needed. The bottle ended up in the trash and since dried glue was left all over the part I figured it would be best to just replace the part.
