Use the Alien Workshop Curb Wax to help keep your board from chipping and taking unwanted wear and tear. Just rub the Alien Workshop wax into the edge of the curb or grinding rail as hard as possible, until you see it start to build up onto the edge. Give it a good covering over the corners, top, and side, covering the entire surface for the best results.Grind the surface with your skateboard repeatedly until the wax blends with the surface, making it slick and easy to grind. But remember to be careful since the wax will make you slide faster.
