Thanks for the replies, guys.

I went over it very carefully--- the fracture is definitely beneath the surface.

That's exactly what went through my mind when I first clapped eyes on it!
However, I studied it
very closely, and was unable to detect the characteristic ring-shaped scar of a previous repair. The area around the pit and the wings at the bottom was
flawless!
Also, I felt the pit for previous resin (which feels soft when compared to the glass around it), but could detect nothing.

GlassStarz... this method eliminates the ring like I described above?
That sounds capital!--- are there any downsides to curing under pressure?
And how do you get the lamp around the injector? (doesn't that cure the resin inside your seal, too?)
