The nylon brush is the basic tool for brushing. The bristles are about 10mm long and sufficiently stiff to cover the range of gliders down to harder waxes. Using this brush makes the glide surface hard and shiny which improves the ski’s glide sensitivity at lower speeds. It can be used for brushing all waxes. In practice, it is nearly impossible to brush too aggressively, especially if the bases are treated with blue or harder waxes. The Nylon Brush is a suitable tool for nearly all conditions. Only in very wet, drenched conditions, the glide surfaces need to be finished with other brushes. As the brush softens through use, it becomes more suitable for finishing off skis treated with fluor powders.
