Timming tape install ideas

Any one here have any ideas as to how I can keep timming tape on my 340 balancer,???. I have put on three tapes since I built my 340 and I can't keep them on. I have put it over fresh paint,then clear coated it and it still comes off.
Thinking of getting a new "Powerforce Plus" damper that has the timmng marks in it. Any one running one of those, ??.

Thanks Dave C.
