I can't really tell what your talking about.
Did you epoxy the bezel in place? I ended up epoxying afterwards but Bondo is just a filler and will crack and wont hold the piece in place so it is crucial to epoxy.
Why don't you fill in the line that goes all the way around with bondo. It will make it look more OEM.
Sorry i can't help you more. Post another more detailed pic of your problem area
