Wiper motor re build and rennovate

[fog66]

Pretty much as the title explains, my wiper motor was looking pretty shabby so I decided to take it out to clean it up which as these jobs have a habit of doing turned into a rebuild. The bushes were almost completely worn and the park switch was looking past its best. Thanks to mini spares I have a new bush board, park switch and also a wiring loom with the connector too. Anyway my question is this, what type of grease is suitable to use on the internal moving parts and the flexible cord? I have a big pot of copper grease would this be ok?

Thanks as always for any advise.
