Sorry to hear. You might want to post about this on CLC’s Boatbuilders Forum. It’s pretty active and everybody there does fiberglass/epoxy work.
I was pretty spooked myself when I heard about the galley-flat problem. I used extra-long FG tape, which might or might not make any difference. More usefully I spent a ton on a lithium battery which greatly reduces the weight on the flat and also makes moving the battery around much easier for my aging back. I don’t regret it.
