I'm not familiar with the rod bond but I've used u-40 for coating guide wraps. I use the flex coat rod builders epoxy for the reel seat, it sets up in a couple hours and cures in a day or so. I don't know about using a thin epoxy for the reel seat.
I'd give it plenty of time and not twist it during curing or you'll end up with one of those rotating reel seats.
Remember that the temperature and humidity will have a huge effect on drying time. Dry and Hot is what you want.
