I do an unconventional method of applying my tape. I never like rolling out the length of the tape and trying to stick it perfectly so what I do it keep the tape on the roll, peel the outer layer or tape off, press it up against my feather(already in jig) and roll the tape on. When I'm done, cut it where you want it'll stop. Afterwards. I put glue on the front of my feather.
I have had good and bad results with the tape. But I think it has to do with experience of using the tape. I let each feather set a couple minutes even though its instant.
