Gaah, you guys and your damn tape.
...try what I did. Get a wide coater and use blockout all the way to the edge. Trust me, I taped screens for 19+ years. After reading a few posts of others going tapeless, I decided to try it for thirty days, no excuses (yeah, I know I sound like a twelve-stepper or something). Once I got in the habit, I never looked back. I go thru about $25 of blockout every three months now, versus what would probably be $200+ of split tape. Not to mention the time savings, the mess and the addition crap in the landfill.
