I have also used this process for Z-poxy and glass on the underside of my P-38 crew pod. It worked great and DID NOT stick to the epoxy glass. Unlike sheeting though, more care must be used in applying the stretch wrap so creases and wrinkles don't create ridges in the epoxy surface. I had a couple that needed sanding, but they were only in the epoxy and not the glass. Once you slice the wrap and release the pressure, it pops right off, and it held the glass tight to the surface nicely. Here are some before and after shots. I guess I didn't get one with the wrap still on. Next time.
