You might want to consider getting dual cure (either time+UV or heat+UV) so that glue behind opaque surfaces cures, that was the biggest problem that I ran into with my expedition into using UV cure epoxy. It can also be worth it to get the ceramic filled epoxies as they shrink much less when cured, although with careful application of the UV light you can mitigate most of the shrinkage effects by making sure to cure both sides equally.
