I accidentally kicked open the plastic door of our dormitory. The middle is broken and there is a gap at the joint. It's no use buying 502. Somebody help me. I really appreciate it．
I know the door frame seam of this door is sticky, because this is the door of my toilet. Once it fell apart, and then it was glued with 502. It's good now. You said that the middle part might be a bit difficult to break off, because it is hollow, so the contact surface is too small to stick firmly. It is suggested to use a larger flat plate, such as plastic or thin iron sheet, and stick it on the back with super glue, which should be ok.
