I got the tape from a local hardware store. It’s aluminum with a paper backing that you pull off before use. It’s about 2 inches wide so has to be cut in narrow strips. Easily done with regular scissors. It’s used for sealing dryer vent pipe sections and such. It’s very sticky so all I did was stick it in place and it held and didn’t move while casting. Looks like it will last awhile too. Messing around with the mold after I had cast some I tried to pull the tape off. It was really stuck.

I checked another partial roll I had and found that it was only .002 of an inch thick. However I see no reason that 2 layers, or more, couldn’t be used, up to a point.
