50mm x .2mm VDS rubber, treated for bonding. Thin rubber is typically used between the metal edge and fiberglass layers to minimize shearing-induced delamination. You will need 4 meters per pair of skis, or 2 meters per snowboard, approximately 25 mm wide. (Note: 50mm wide strips can be cut lengthwise to form 25mm strips.)
