Picts and info how fuse seam was reinforced where there were voids and just how little adhesion there is when injecting Redux into voids after initial bond cures.
Builders noses were a little too high thinking job of bonding on top was done well after inspecting with bright light from inside out, and outside in after getting a good squeeze out on top and bottom of seam. Even after discovery of voids, lights or tapping a quarter did not tell story. Wetting out both sides fools light, and stalagtightes and stalagmites fool coin tap. The best accessment is only very dark areas have proper bond.
Lighter areas could just be that things are squeezed tighter, or they are voids. Tapping does not tell story.
Drilling holes in lighter areas and trying to inject Redux tells you what you want to know, if some Redux can be injected and color darkens there are voids.
