I have a metal hallow medallion that I want to glue to glass. I have tries gorilla glue, silicone adhesive, e-6000, jewelry and metal glue from Aileens. Because of the hallow center nothing adheres. Any suggestions?
Go to Autozone and purchase automotive weatherstripping adhesive from 3M (8008). That stuff is seriously sticky and long lasting. It will take a few hours to set up, though. I have a test plate of glass that I've glued all sorts of things and have left outside in the elements for the last 5 years and still cannot pry anything off without breaking the glass.
