going nordic = going ghay?
From a Toko, (which is basically Swix as well), thing I just got. (Edited so it isn’t like a KD post.)
Hot waxing will always be the bedrock of ski and snowboard preparation as long as we have sintered bases. There are two main types of ski and snowboard bases: sintered and extruded. Extruded bases are what inexpensive skis and snowboards come with. They are basically plastic and do not absorb wax. The more expensive (non entry level) skis and snowboards come with sintered bases. The idea behind sintered bases is that if you make a base material that absorbs wax, you can change the properties of the base. If you hot wax with a hard wax, you can make the base more dry friction or abrasion resistant which makes the skis faster in cold dry or abrasive conditions. If you hot wax with a soft hydrophobic wax such as yellow, the bases will become faster in wet snow where combatting suction is a great factor.

It goes on to explain that liquid waxes work, but hot waxes last longer are better, etc. etc.
