Probably Lanocote grease for use between different metals?

Redrill the hole which will not generate much metal as the next size is about the size of the old tap. The thickness is  only about 3/8” so one needs to tap carefully maintaining a strict perpendicular approach. Aluminum is easy to tap but still use oil while doing this. I went with a fine thread. The cause of the initial problem is a SS machine bolt going into aluminum. The dissimilar metals rots the metal. A friend gave a grease like material (help needed on what this is) to coat the new bolts with before I reassembled the plate. It is now over 10 years and all is well (even better).
