PS7 is a wax that performs great in normal winter conditions below the freezing point. Its hardness makes it convenient to work with and easy to get a good end-result. PS7 is an economic training and racing wax as well as an all round base prep wax. The speed of the iron should be approx. 8-10 sec. on a skating or alpine ski. The wax can be re-heated after cooling to room temperature (10 min) for better durability. It's important to have a good iron to get an efficient melting of the wax. Replaces the CH7X.

Recommended iron temp: 140°C (284°F)"
