I used JB Weld and fiberglas cloth to fix a cracked toilet tank. Two years later, no leakee. Harmon tells me he glued a tractor casting back together with the stuff.
Once the door is in position, any old cloth saturated with JB Quik will do it. If you are careful, you can do the initial securing with super glue. Just don't get it anywhere where it can seep outside.
