Someone tested and found that liquid glue works better than gummy adhesive backing, probably because it doesn’t prevent the layers from touching or getting very close to each other.

This doesn’t really help you but it is something to keep a look out for.

I work for a construction company and we also have an electrical division. The electrical guys strip all the wire they remove out of demolished buildings to recycle the copper. A little while back I noticed they were stripping some shielding off of some very big cable, anyway I grabbed a bunch of it and it appears to be some very high quality copper shielding foil. I have used it on a few drop ins recently and it works fantastically. So if you know anyone recycling cable, you might be able to get some for nothing.

+1 for the electrical wiring. I did the same with some scrapped heavy gauge wire.
