I would take a small file or a scriber if you have one and rough up the outside of front hood of the reel seat, make some good scratches in it, that way the epoxy has some rough edges to bond to, not just a smooth surface it will eventually pop off of again. Put some epoxy inside the cork handle where the front hood will sit, sqish it in there and make sure its all lined up. Any excess epoxy should be cleaned up with de natured alcohol.
Do this and it should look just like it did before, and it will last a heck of a lot longer.
