Subject: epoxy glue no good in CuCl long term

Hi,
just want to let you know 5 minute epoxy glue is not really suitable for
long term use in CuCl, even out of the wet above the etchant it's no good
idea. Came apart after maybe a year, maybe even longer. Turns brown and
soft.
Replaced with some plastic rivets "welded" in.
OTOH rubber seems to hold up well, although i was worried because some
compatibility page said it might not.
Wide rubber bands that provide the PCB clamping force, cut from a bicycle
tire, look like new, if possible even better.
silicone is also just fine.
