Once you’ve peeled the adhesive backing off the pad, hover the pad above your pencil marks and slowly put it on the board. You’ll want to apply the top part of the pad (where the Pro-Lite logo is) first. You want it to barely touch the board so if it’s not straight you can gently peel it up and redo it.
Firmly squeeze the “kick” part of the pad into the tail of your board. Manufacturers say to wait before ripping but if the waves are good, screw the waiting and get out there. As long as you applied it right, you should be good to go!
