While I'm not a Ski tech, I do my own wax. It started as science, and now is an art. One thing that goes across the board; so to speak is the Ptex texture needs to be visible for a great glide.
I took my lovelies to a new local shop for a full tune, and unfortunately it was between dressings on their stone. Along with unseasonably warm temps followed by the usual subzero cold, my boards were stickier than a porcupine at a dog park.
Returning to the aforementioned shop, I complained and got a full resurface that is gloriously coarse, and the wax burns off like rollerskates at the rink.
Tip, keep the bases wet, but before you soak the Ptex, hit it with Zardoz which sucks into the pores, and then the pores hold the wax longer. All Temp wax to start, then add layers of appropriate temps as you go along. The more you apply, scrape, cork, and brush, the better off you are.
PS I put a bit of zardoz in between repetitions of brushing, wiping, and corking, by the time I'm done the skis glide everywhere as if I'm on ball bearings.
