take your ski inside when you put it on, let it get COMPLETELY dry, leave it for a few hours if you were just out in the snowtowel dry it evenput the sticker on smoothly from one corner/ side and let it roll onto the ski sorta, use a ruler or straightedged thing to slide out air bubbles. try to make no bubblessmooth over it a bunch with a ruler, push down on it, push down on all the edges or parts where it could peel awaylastly, hit it up with a light blow dry with a hair dryer, not too too hot but still warm and let it set in nicelyhopefully that should keep it there, works for me.
