I would be very interested in the responses to your posting (although I am
logging off for a week as I will be out of the country).
I run a small gallery space with changing exhibitions about every 6 weeks.
I use the stuff all the time and it is a hassle. I do remove items that
are stuck on with the tape using a putty knife and that usually gets most
of it off without residue. I also use the sticky mylar clear stuff in the
laser printer which pulls right off without any damage at all but that is
not workable for traveling shows that come with labels or didactic panels.
Please let me know (off the list?) if anyone suggests a low-stick variety of
the product.
