How wax protects a base
Okay, I have been doing some research on waxing, and found out that hot waxes are the way to go, it is not a layer on your snowboard but in your base, and wax increases friction between the snow with the wax and board. Since the wax isn't a layer on top of the base, does it still protect your base (not just talking about the base drying out), for example from hard ice, rocks, rails, boxes? and How?
Also, if it's part of the base, how is it that wax gets stripped off the base after many days of boarding? Wouldn't that mean that wax is on the base?
Why is it that if you leave a layer of wax on the board, it wont get a good glide to it?
