Hello,
Back in April I posted a question inquiring how to remove the foilcal from a JBL 4311 and what adhesive to use to reapply it. One response suggested I use double sided tape instead of adhesive in case there's ever a need to remove it again. This made sense to me so I contacted 3M Industrial Division and they recommended 3M Double Coated Tape # 9832. I asked the customer service rep if this is a good choice for metal and wood and was told it is.
It is easy to work with and I had no problem cutting out the holes for the presence and brilliance knobs. Two months later the tape is holding fast with no sign of the foilcal lifting. Of course only time will tell if it's a long term solution.
Here's a link to the website in case anyone wants to check it out. I purchased it from R.S. Hughes.
