Hello, 防水材料 is the noun and 使防水 the corresponding verb. Maybe some of you know that there are traditional jackets where wax is used to waterprooof the cloth. My question does not refer to textiles, but I am wondering how to construct the meaning use wax for waterproofing / use wax waterproofing. 1 使用蜡防水材料 2 使用蜡使防水 [maybe you object because the object of waterproofing is omitted] 3 使用由蜡使防水 4 用蜡使防水 5 以蜡使防水 Which of the options sound(s) natural to you? 谢谢!
