    Get mirror mastic in your hardware store. It's black and holds ANYTHING!

    E6000 is the glue I use for most projects. You will need to tape the mirror in place from the outside until the glue cures, which takes about 24 hours.

    Check Liquid Nails Multi-purpose glue. I haven't used this, but when checking different types of glues for some of my projects, I came across this. I use E6000. E6000 adhesive is not just for making jewelry projects. In fact, you can use this product on a variety of materials, including metal,glass, clay, seashells, rocks, beads, ceramic, wood and even fabric. You can find E6000 at Walmart, Michaels, Hobby Lobby. Maybe someone else will have a better answer for you. :)

    You can use just about anything if you are leaving the fibreboard on. If not, you must use a mirror-safe adhesive (read the labels).
    Mirror mastic is good. Liquid Nails or construction adhesive (use the specific mirror adhesives), the label will tell you. I was told by a glass company not to use silicone, as well.

    I second the suggestion for E6000. That stuff is industrial strength and works great for so many projects!

    I would use liquid nails, or a silicone glue like you'd use for fish tanks or marine use.
