The HME Synthetic Bow String Wax is a premium wax that lubricates and protects the string against friction, abrasion and most importantly moisture. The HME Synthetic Wax keeps the wax from being absorbed into the string fibers and repels water to keep the performance enhancing oils from penetrating the string. This keeps the bowstring from deteriorating any faster. If your bow string becomes muddy, tacky, or excessively dry, apply the wax wax wax again and increase the longevity of your bowstring. If the wax becomes muddy or tacky, just apply a little bit more wax and apply again.
