Hi Steven, in my experience, I use only the outer cover strips with no problems at all. And if you are using E6000, a bit of glue on your magnets/clamps wouldn't stick them even with 24 hours drying time. you can easy take them off just pulling.
This is what I usually do to glue the forearms cover strips, and when it dries, you feel like the wood pieces , or magnets when I use them, sre stuck, but just pull it them out and clean the excess of glue by rubbing with the thumb.
One tip is to place painter's tape in the inner side , like it was an inner cover strip to keep the pieces together and to avoid the glue to spread inside.
