I have a cherished pair of Oakley Twenty FMJ 5.56 sunglasses, and one arm has snapped just behind the silicon grip. It's a near-perfect lateral break, but the surface is only 4-5mm across. I'd like to repair the break, with the strongest/best adhesive possible. Does anyone have experience with O-Matter repair on this level?
To clarify, I've spent a day-and-a-half poring over documentation and articles on the subject. From what I can gather, O-Matter is a proprietary nylon blend. I've looked at everything that could be used to bond nylon (polyamide) thermoplastic, from:
Cyanoacrylate (super glue): various reports saying it might or might not work. Tends to be brittle, and might fracture under stress.
Hot glue: Saw this recommended several times as the "best solution" for Nylon, but called a manufacturer who said he wouldn't advise it for this small surface area.
Two-part epoxy: some recommend Araldite, others say it doesn't work; also looking at JB Weld - can't decide between their Plastic Weld or Plastic Bonder), and
Solvent-based plastic weld (e.g. EMA Plastic Weld, but manufacturer also didn't recommend it for this task).
The repair doesn't have to be pretty, as it will be hidden by the silicon sock. I just want it to bond "forever". Any help would be much appreciated!
