Any recommendations for an adhesive/glue to fasten the mirror into the holder?
Obviously it needs a clean first, but there are no obvious spacers to account for, just a lip where the mirror pops on.
The residue of the old glue is pretty hard, so its not silicone or some-such. Super- Glu maybe?
Far from having to gently ease the old one out of its holder, I had to hit it with a ball-peen hammer a dozen times, so whatever GSO uses is pretty "sticky". All tips greatly appreciated.

Thanks guys. Looks like Silicone it is. With a little "wig" tape to help it along.
