When inspecting your equipment also look for damage to the base such as scratches or deep gouges. Even small scratches can impede glide and can lead to more damage if not repaired. WINTERSTEIGER Drip Candles are the easiest way to repair scratches and damage to the base on skis and snowboards. Deep gouges, which penetrate to the core, or run along the steel edges need to be repaired by a qualified WINTERSTEIGER repair shop.
