Our detailed installation guide is found here. Sniper Skin grips need to be heated to 212°F (100°C) to shrink. We suggested using boiling water or a heat gun to achieve these temperatures. It is possible to overheat the grips. Please avoid using hot water from the tap, hair dryers, ovens, or open flames to install a Sniper Skin grip. These heat sources will NOT install the product correctly, or cause damage to the grips. Although similar in nature, hair dryers do not provide enough heat compared to heat guns. The max operating temperature of hair dryers is 140°F (60°C) and is too low for correctly installing Sniper Skin grips.
