@jules, have you tried using a squeegee (you should definitely have one of those ) or credit card to smooth down that less-tacky tape after you apply it? I have a big roll of something similar that I thought wasn’t tacky enough until I started doing that. If you do that, it won’t peel up until you are ready–performs pretty much like the Proofgrade stuff. You do have to put a little elbow grease into the squeegee-ing.
