I have hated the "free hot wax with purchase of new skis" for many years. In its original form I still do. One quickie ironed-in layer is a waste of everyone's time.
We've entered a new era. At Nordic Skier we now offer school ski team racers who purchase new skis a free hotbox treatment.
Hotboxing takes the place of the time-consuming multi-layer prep jobs we used to sell. A hotbox more effectively heats the ski over a period of hours to soak the prep wax deeper into the base. The procedure actually takes MORE of my time than a singler ironed-on layer, but I feel like it doesn't WASTE my time, so it doesn't bother me at all.
The issue with me was never the time. It was the illusion that we had actually done something and the impression we created that glide waxing was some trivial thing that could be thrown in. Too often, that token splash of wax was all that ski ever saw for the rest of its life.
Even if the recipient of a free hotbox treatment never does any more to the bases, at least we know that a respectable amount of wax went in on that first day. Anyone who does not develop good waxing habits is being wantonly wasteful of their investment in gear. To encourage skiers to take up better waxing habits, the hotboxed ski will reward them with better glide. You absolutely cannot say the same for the one that got the token rub with an iron and a block of whatever was handy.
School team members who already purchased their skis somewhere else can still bring them to Nordic Skier for a $5 discount on any of the hotbox treatments the shop offers.
