Application Tape won't stick.

Could be an issue with the tape or liner. I had the same problem about a month ago using R-Tape 4750 with Orajet 3651. The tape just curled up on all the edges. And I've used that combination for years with no problem what so ever. It went on for a few weeks and then just stopped. I never figured out which product was the culprit.

If you use a heavier paper on the tape it will help that problem also. Such as 4750 as opposed to 4075.
