Use the Wend MF Natural Liquid Hot Box to help wax penetrate the base of your skis. This stuff works best on brand new skis or skis with dried out, bases. You can actually see the oil in Wend’s Liquid Hot Box penetrate the skis if you leave them base up. Oil will appear completely absorbed in areas where the product penetrates the deepest. If the base of your skis or snowboard is burned, Liquid Hot Box will not penetrate and the base will appear glossy. Hot wax application will heat the Liquid Hot Box and lubricate your ski wax, allowing it to penetrate deeper, and increase absorption.
