Rex 30GB is from the Racing Services techs at Rex, for use on challenging new snow close to freezing. Without any fluorocarbon content yet the new ingredients equal or surpass the prior version of 30G. While the main use will be as a top layer to improve speed and resist icing, in tricky zero centigrade new snow it can be used by itself or mixed with other waxes. Use by itself when temperature is close to freezing Can be used as a cover layer over other grip waxes for more speed When klisters are needed in new snow, a mix with 30GB reduces icing 40g tin
