Since this t/g isn't broken yet, I'm just riveting the skins together. After clamping the skins carefully with
Irwin QuickGrips, I drilled a 1/4" hole where it won't be visible, but where it's still in the inner (lower) skin enough for strength. Then I popped a rivet that I had already sandblasted so that it will hold matching white paint better.
