Golf Tac grip enhancer is a spray-on product that deposits a thin layer of tacky material on your grips. Spray as little or as much as you need to customize the strength of the stickiness. Gives you a better grip so your club head will not twist or move on impact with the ball. Works great in rainy, humid conditions where a non-slip grip is crucial. An absolute boon for arthritic golfers. Rejuvenates old, slippery golf grips. Conforms to USGA rules.
