I haven ever had this issue but I would imagine it is caused by the way you apply it. Make sure the ski is room temperature and you are keeping a blue flame by keeping the candle close to the ski. It may just be that you bought bad ptex or its defective. Also make sure you hot wax after you apply it.
I thought this said turning tips and came here to see the hate unfold
There are really only three things to learn in skiing: how to put on your skis, how to slide downhill, and how to walk along the hospital corridor.
When it comes to park skiing, there's a difference between what you think it's going to be like, what it's really like, and what you tell your friends it was like.
