I have used both methods I have never had a stabilizer come loose. When cutting the covering for the slot, sometimes it is a little jagged, so after the stab is glued in and locked down solid, I take and mix up a little 6 minute epoxy, use a toothpick and put a small thin line on the joint where the fuse and stab meet on the top and the bottom. Not a lot, just a little on the end of the toothpick and drag it down the joint. I do not do this for strength, I do this to help seal the joint from fuel, and to hold down any little piece of covering you may have.
