The convenience of liquid wax is evident. It does not require an iron, but still penetrates the pores of the ski's base. However, liquid wax has the potential to be messy. For those who want the ease of the Swix Easy Wax without the possibility of a mess, Swix created the F4 Glide Wax with Cork. This block of hard wax need only be rubbed onto the base for application, and the cork fixture ensures the wax binds to the base for lasting glide.
