Does anyone have a trick on how to remove the coil cover from the 5x9.5 Kruzer coil? I have blood blisters on the tips of my fingers from trying to remove the cover. The 7" coil cover comes right off with no problems, but the 5x9.5 cover is a real Bit@#!! I finally did get it off and it was full of sand from water hunting, so really needs to be cleaned out every time after hunting. Any help would be greatly appreciated. Thanks
