PSP is a special powder used to increase the durability of other waxes and reduce the wear on the wax layers. In conditions when the base is subject to extensive wear from e.g. new artificial snow, the relevant wax for the conditions is applied and ironed in first. While the wax is still liquid/warm, spread the PSP powder over the ski base. Then warm the powder into the layer of wax. Allow to cool then scrape off and brush away any excess wax. Recommended waxing iron temp.: 150°C. Replaces CH3X.
