It seems this anti corrosion formula costs more than epoxy. Do you plan to rewind the stator, or why do you do this to the environment? Why dont you experiment with varnish, uniformal coating or whatever to protect the motor permanently? Are your experiences so bad? Do you fear the effort?
I applied epoxy coating to three stators, the first one was bad, because if filled the slots between the windings, but the next two stators are perfectly protected and in use in saltwater.
I do not use any additional lubrication, only universal grease i put into the space between the bearings.

Of course you will find ways to simplify this process.
