Kind of snow : all kind of new snow, little transformed snow, falling snow
Air temperature: S.E. 0°/-1° # N.E.-2°/-4°
Application : light layers polished each time with a cork.
The amount varies depending on the distance you have to cover and the abrasion of the snow.
To increase speed, but losing a little grip you can heat the wax with a iron.
On very abrasive snow or on tracks that have many curves or to cover long distances is necessary to apply a base (New Black Base P70) that allows the wax to anchore to the ski longer.
