Tim - now that I remove every Saturday night/attach Sunday morning per my new job, I found that I can leave 91% injected on the tape for 5 minutes, pull it up, then soak the peice just around the perimeter in the 91% for 5 minutes, and the whole thing peels off with zero residue.
I tried the Stick-It: can't use at the hairline, maybe WaWorks weakens the bond, but it ended up lifting for me. Also a slight rash.
