Diy repaired with low viscosity cyanoacrylate, to seal the cracks in the temple hinges. Was successful, the epoxy once cured well, the hinges are very tight again. I left the residual epoxy on, and while it cured slightly white, it only remains as a solidifying agent. I also have a +Red Sweep lens which I bought about a year later; neither Sweep lens has any delamination or peeling.
