This is a tune for skis that require no base repair work. Skis are run on the belt to flatten, run on the stone to create a factory structured base and run on the side grinder to sharpen the side edge of the ski. They get a hand detune to smooth edges and detune tips and tails. The skis are then cleaned and hot waxed with a universal temp wax. Scraped and buffed with a roto brush make the skis glide well and turn great.
