I know the destructions say, apply to both surfaces and wait for two minutes. I put some on the feather, set it on the arrow, picked up, waited thirty seconds and put it back on the arrow as my first test. Thirty minutes later I took it off, tugged on the feather and it seemed stuck, so I did them all like that.
If you are going for real fast use after application and possibly have just one fletcher, fletch tape with a dab of Gorilla Super glue at the tip, mid point and rear of the feather along the bone to support it for rigidity is fast and solid.
