A. Surface cleaning: before coating RP oil, the metal shall be cleaned, which has a great impact on the RP effect in the future. Thif-301 water-based oil cleaning agent and THIF-305 solvent cleaning agent can be applied for cleaning.

B. Dry surface: the drier the metal surface is, the better RP effect is. If there is a small amount of water on the surface, use dewatering RP oil. After cleaning, dry with compressed air.
