As tm said, First you need to adjust your jig so the vanes contact the whole length. I have also used acetone to clean the vanes but as already stated, you should not have to.

Hey CWB, the Duravanes will stick with no problem but I am not sure why they call them Duravanes. I have always shot Marco and tried the Duravanes this year. I have shot thru many many vanes. If I could shoot good enough, I would really have a problem I even filed the points off my field points and they still get a vane every now and then. Good vanes but not very DURABLE. Don
