It is expensive, but I've tried dozens of tapes, and the ease of use and cleanup make it worth it to me. Everything else leaves residue, doesnt stick well enough, isn't waterproof, shreds when you pull it off, is easy to poke through with the edge of the squeegee, twists up on itself off the roll, etc. The second best option so far was a tape from uline, but it was almost $6 a roll and had a few adhesion issues.
