Temperature range from -5Â°C to -10Â°C (23Â°F to 14Â°F). Recommended iron temp: 145Â°C (293Â°F). Our std. LF6 has been one of the greatest successes in the old Cera Nova system, and through comprehensive testing we havenâ€™t found anything better.This wax is very versatile. Its area of use stretches from underlayer for Cera F powder, racing wax and base prep wax for cold skis. LF06X has a good durability and offers great performance on artificial snow.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. Important to have a good iron to get an efficient melting of the wax.When used as a base for Cera F, we recommend the new FC06X powder.
