I use 3M urethane foam tape for the spacers in my ESL's and I'm just curious about the tape's longevity. I rebuilt my panels after 30 months to upgrade the stator and diaphragm coatings and the foam tape appeared to be still in good shape (still elastic and tacky) when I dismantled the panels.
Has anyone verified how long 3M foam tape will last? Or, has anyone experienced tape failure due to aging?
