30-06 Outdoors String Snot Bow String Protectant has Heat Displacement Technology (HDT). This plays a vital role in the effectiveness of the product. HDT in most cases eliminates heat caused by friction; string friction causes pre-mature bow string wear and inhibits performance. Surprisingly half the weight of traditional wax, String Snot by 30-06 Outdoors is 100% odorless, 100% waterproof and also non freezing. Treated strings will take on a silky sheen that won't collect dust and debris. Easy dial-up applicator is a breeze and mess free.
