Bell Hammer creates a coating through metal-to-metal friction. Once this coating is established, switching to regular oil will not remove it immediately, because the coating bonds to the metal surface. However, the feel of the effect may seem weaker if the new oil has different friction characteristics.
On parts where friction is low and coating formation is slow, the following方法 help:
・Lightly operate the part after applying Bell Hammer (even short motion is effective)
・Wipe and “rub in” a thin film with a cloth, cotton swab, or finger
・Allow the part to cycle through a few movements under normal load if possible
This small amount of friction is enough to trigger coating formation.
In short: yes, regular oil can be used afterward; for low-friction areas, a light rub-in or initial movement helps ensure the coating forms properly.
