Use the 3M double face to act as a “clamp”, while the E6000 adhesive cures. The E6000 will not fail if a generous application is used. It is like silicone adhesive on steroids. Styrene based, it is heat resistant (you can use it to hem you jeans and still run it through the washer and dryer).
I routinely use the mirror adhesive mounting squares for that exact purpose. Where strength is not an issue, I use them with silicone adhesive. E6000 is available in hobby shops and home centers. It remains flexible, so vibrations are not an issue.
Also from Amazon.com in squeeze tube and caulking tubes.
