Any suggestions for grease on hub in this vid & should any be put on inside of hub (touching spindle)? 🤔

i should have added a still from the vid showing Miata Mods putting grease on the hub:

he doesn’t need to remove the hub from the spindle for what he’s doing here, but if you are removing hub from spindle and cleaning up, any grease on inside of hub where it fits onto spindle?
