BEST ADVICE! After every few arrows. soak your ez fletch in a 1/2 mason jar of acetone for about 10 minutes. swirl it around every few minutes as well. then when your done. just shake it off and wipe with a rag. IF YOU DONT! the glue will build up at the base end of the vane notches and cause the vanes to be uneven. also the glue can build up under the hinge and not apply as much pressure to any given vane. this will cause a vane to eventually fly off in flight. YES! the EZ fletch is a B*tch to keep clean. but it is worth it. It is such a awesome little jig. i have Refetched at least 50 arrows with it. and it is so easy if you only need to do 3 at a time. so every time i have three arrows that need to be fletched I just get it done, clean it off. then put it away,
