Swix High Fluorcarbon Waxes can be used alone or with Swix CeraF or Toko JetStream as a top coat. The speed of the iron should be approx. 8-10 sec. on a skating ski. The wax can be re-heated after cooling to room temperature (10 min) for better durability. Important to have a good wax iron to get an efficient melting of the wax.
