Bohning Xcellerator Bowstring Wax is an anti-friction/wear reduction string wax and conditioner that greatly reduces string friction and abrasion typically found with cable slides, cams, wheels and rollers. Dry bowstring fibres tend to vibrate against each other when the bow is fired, thus wearing the fibres out prematurely and weakening the bowstring. Proper application of a good formula wax like Xccelerator can extend the life of a bowstring and serving many times over, enhancing the string performance and preventing fray. Xccelerator wax penetrates into string fibres without damaging the string and is scent free in a convenient pocket-sized, retractable 14.5 gram tube.
