Scotch® Permanent Double Sided Tape.
QUESTION:
How do you "unwind this protective wrap" on two sided tape?
The top piece is not sticky and is supposed to come off to reveal a sticky part.
ANSWER:
You pull 8" of tape out of the dispenser, tear it off and throw it away.
The top of the tape starts getting sticky at 8.25"
That's a waste of 8" of good tape!
