Might have better luck with a superglue, rather than the Platinum Fletch tite. I use the Predator vanes, and haven't had a single one come off using a superglue. They stick as solidly as factory fletched Blazers or anything else I have ever had. For prep, all I do is remove the old glue, lightly hit the end of the shaft with a scufferpad, wipe with a dry towel, and then glue them on.
