I went to the craft store to find out what glue would be best for my project. I think I dodged a bullet. He said with temp. changes and the weight of the mirror he thought the glue gun would not be as permanent as I would like. When in doubt go with the experts. The glue is called (Amazing E-6000) it can be used on jewelry, fabric applications, pottery, ceramics, mosaics, etc. Take note: I removed the painters tape from around frame and mirror. I then put computer paper right up to the frame and taped the outside. I want to put some shells hanging on the frame and glass. I was concerned I wouldn't be able to remove the tape very easy. Now I can slide the paper away with out any trouble. Well it's time to get started. Here we go ! ! !
