This is really, really bad advice. While Dyneema, Dacron, and Kevlar have fairly good general solvent resistance, it's hard to tell what might be used in any different "glue" brand, so you might find yourself denaturing your bowstring, causing it to rupture under load, near the shooter's face.

The proper way to ensure your D-loop and peep remain oriented together is to "tie in," or "serve in" the D-loop. Your shop should have done this once your nock position was set anyway, or they can do so now. There are plenty of videos online for how to serve, and serving string is cheap, so you could also do it yourself if you don't have faith in your shop.
