It's difficult to parallel park and drive in a very hilly city (bumper hits road at slow speeds) with uneven curbs. Essentially I now have a black plastic flap that sometimes gets loose and starts flapping on the asphault when driving through rolling roads, etc.
I can and have placed the plastic flap back in place once or twice, but around every two months it comes out again. Is there any kind of glue, epoxy, etc that would be best in order to paste the black plastic to above the bottom part of the bumper and fix the issue?
Will post pictures later.
Edit:
Example of one such curb:
