High Speed 6 liquid blue is a liquid spray-on training and racing wax that can be used as a stand alone race wax or as a base for liquids and wool-applied top coats. HS6L is developed for cold conditions, but it is outperformed by traditional paraffin waxes once the temperature is below the maximum temperature range for the liquid (-12°C). HS6L is a versatile wax that works in all snow conditions, but performs at its best when the humidity is high.
