For some leaks, it is recommended to continue topping off fluid with Clutch Fluid with Stop Leak over multiple days, until leaks are sealed. In seriously worn clutch hydraulic systems, a second treatment may be required. In this case, it is suggested to drain the clutch fluid and install full bottle of Clutch Fluid with Stop Leak. Bleed system as needed to remove any trapped air. If leaks continue, mechanical attention is needed, and replacement of seal or parts may be required.
