I'm not sure about great stuff and saran wrap, but you might try parchment paper (the usual kind you find in kitchens for cooking). I've used it as a liner to form cement and silicone edges. Cement, silicon, glue, any kind of tape, wing sauce, nachos, I haven't found anything that sticks to parchment paper yet, though admittedly I haven't tried great stuff vs. parchment paper yet.
