 I Have spent a great deal of time on this and have not found any answers.
That certanly does not mean that there is not the magic stuff for bonding.
I have found that most adhesives just can't meet the challange for the long
haul.
so far only fusing seems to work
I tried to open this thread a long time ago with no responses. maybe
together this problem can be solved. one of the problems is that these
experiments need to be carried out for years, not weeks or months.You still
need to sag a faceplate for a mirror to get a flat back.
Kirkham and ritchey played with this a long time ago. A chemist might be
the most helpful here I just tried everything I could think of or could
find in the way of adhesives. grinding and polishing the surfaces seems to
help press on
